Ukukhiqizwa kwe-Caustic Soda.
I-Caustic soda (NaOH) ingesinye sezitokwe ezibaluleke kakhulu zokuphakela kwamakhemikhali, ezinomkhiqizo ophelele wonyaka we-106t. I-NaOH isetshenziswa ku-organic chemistry, ekukhiqizeni i-aluminium, embonini yamaphepha, embonini yokucubungula ukudla, ekwenzeni izinto zokuhlanza, njll. I-Caustic soda ingumkhiqizo ohlangene ekukhiqizeni i-chlorine, i-97% yayo ethatha. indawo nge-electrolysis ye-sodium chloride. I-Caustic soda inomthelela onamandla ezintweni eziningi zensimbi, ikakhulukazi emazingeni okushisa aphezulu kanye nokugxila. Nokho, isikhathi eside kwaziwa ukuthi i-nickel ikhombisa ukumelana nokugqwala okuhle kakhulu kwe-caustic soda kukho konke ukugxila namazinga okushisa, njengoba uMdwebo 1 ubonisa. Ukwengeza, ngaphandle kwalapho kugxilwe khona kakhulu namazinga okushisa, i-nickel ivikelekile ekucindezelekeni okubangelwa yi-caustic-c... -
Ukusetshenziswa okuyinhloko kwe-paste pvc resin.
I-Polyvinyl chloride noma i-PVC wuhlobo lwe-resin esetshenziswa ekukhiqizeni irabha nepulasitiki. I-PVC resin itholakala ngombala omhlophe kanye nefomu lempushana. Ixubene nezithasiselo nama-plasticizers ukwenza i-PVC inamale inhlaka. I-Pvc paste resin isetshenziselwa ukunamathela, ukucwilisa, ukugwedla, ukumboza isifutho, kanye nokwakheka okujikelezayo.

I-PVC yokunamathisela i-resin ingaba ngokwezifiso ... -
17.6 billion! I-Wanhua Chemical imemezela ngokusemthethweni ukutshalwa kwezimali kwamanye amazwe.
Ngobusuku bangoDisemba 13, i-Wanhua Chemical ikhiphe isimemezelo sokutshala imali kwamanye amazwe. Igama lenhloso yokutshalwa kwezimali: amathani ayizigidi eziyi-1.2 we-Wanhua Chemical/ngonyaka we-ethylene kanye nephrojekthi ye-polyolefin esezingeni eliphansi, kanye nenani lokutshalwa kwezimali: isamba sokutshalwa kwezimali esingu-17.6 billion yuan. Imikhiqizo esezingeni eliphezulu esezingeni eliphezulu yemboni yezwe lami ye-ethylene ithembele kakhulu ekuthengisweni kwamanye amazwe. Ama-polyethylene elastomers ayingxenye ebalulekile yezinto ezintsha zamakhemikhali. Phakathi kwazo, imikhiqizo ye-polyolefin ephezulu efana ne-polyolefin elastomers (POE) nezinto ezikhethekile ezihlukanisiwe zincike ngo-100% ekuthengisweni kwamanye amazwe. Ngemva kweminyaka yokuthuthukiswa kobuchwepheshe obuzimele, inkampani isikwazi ngokugcwele ubuchwepheshe obufanele. Inkampani ihlela ukusebenzisa iphrojekthi yesigaba sesibili se-ethylene eYantai Ind... -
Imikhiqizo yemfashini nayo idlala ngebhayoloji yokwenziwa, iLanzaTech yethula ingubo emnyama eyenziwe nge-CO₂.
Akulona ihaba ukusho ukuthi izinto eziphilayo zokwenziwa ziye zangena kuzo zonke izici zokuphila kwabantu. I-ZymoChem isizothuthukisa ijakhethi ye-ski eyenziwe ngoshukela. Muva nje, umkhiqizo wezingubo zemfashini wethule ingubo eyenziwe nge-CO₂. UFang yiLanzaTech, inkampani yenkanyezi yokwenziwa kwezinto eziphilayo. Kuyaqondakala ukuthi lokhu kubambisana akuyona "i-crossover" yokuqala ye-LanzaTech.

Izindlela Zokuthuthukisa Izakhiwo ze-PVC - Iqhaza Lezengezo.
I-PVC resin etholwe ku-polymerization ayizinzile ngokwedlulele ngenxa yokungaguquguquki kwayo okushisayo kanye ne-viscosity ephezulu yokuncibilika. Idinga ukushintshwa ngaphambi kokucutshungulwa ibe yimikhiqizo eqediwe. Izakhiwo zayo zingathuthukiswa/zilungiswe ngokwengeza izithasiselo ezimbalwa, njengezinzisi zokushisa, iziqinisi ze-UV, ama-plasticizers, izilungisi zomthelela, izigcwalisi, izinqamuleli zamalangabi, i-pigment, njll. Ukukhethwa kwalezi zithako ukuze kuthuthukiswe izakhiwo ze-polymer kuncike esimisweni sohlelo lokusebenza. Isibonelo: I-1.Plasticizers (i-Phthalates, i-Adipates, i-Trimellitate, njll.) isetshenziswa njengama-ejenti athambisayo ukuze kuthuthukiswe ukusebenza kwe-rheological kanye nemishini (ukuqina, amandla) kwemikhiqizo ye-vinyl ngokukhuphula izinga lokushisa. Izinto ezithinta ukukhethwa kwama-plasticizers we-vinyl polymer yilezi:I-Polymer comptibili... -
Isihlalo esiphrintiwe se-polylactic acid 3D esichitha umcabango wakho.
Eminyakeni yamuva, ubuchwepheshe bokuphrinta be-3D bungabonakala emikhakheni ehlukahlukene yezimboni, njengezingubo, izimoto, ukwakhiwa, ukudla, njll., bonke bangasebenzisa ubuchwepheshe bokuphrinta be-3D. Eqinisweni, ubuchwepheshe bokuphrinta be-3D basetshenziswa ekukhiqizeni okukhuphukayo ezinsukwini zakuqala, ngoba indlela yayo ye-prototyping esheshayo inganciphisa isikhathi, amandla abasebenzi kanye nokusetshenziswa kwempahla eluhlaza. Nokho, njengoba ubuchwepheshe bukhula, umsebenzi wokuphrinta we-3D awugcini nje ngokukhula.

Yiziphi Izinhlobo Ezihlukene zePolypropylene?
Kunezinhlobo ezimbili eziyinhloko ze-polypropylene ezitholakalayo: ama-homopolymers nama-copolymers. Ama-copolymers aphinde ahlukaniswe abe ama-block copolymers nama-copolymers angahleliwe. Isigaba ngasinye silingana izinhlelo zokusebenza ezithile kangcono kunezinye. I-Polypropylene ivame ukubizwa ngokuthi "insimbi" yemboni yepulasitiki ngenxa yezindlela ezihlukahlukene ezingashintshwa ngazo noma zenziwe ngokwezifiso ukuze zifeze kangcono inhloso ethile. Lokhu kuvame ukufezwa ngokwethula izithasiselo ezikhethekile kuyo noma ngokuyikhiqiza ngendlela ekhetheke kakhulu. Lokhu kuvumelana nezimo kuyisici esibalulekile. I-Homopolymer polypropylene iyibanga lenhloso evamile. Ungacabanga ngalokhu njengesimo esizenzakalelayo se-polypropylene material. I-block copolymer polypropylene inamayunithi e-co-monomer ahlelwe ngamabhulokhi (okungukuthi, ngephethini evamile) futhi aqukethe noma iyiphi... -
Yiziphi izici zePolyvinyl Chloride (PVC)?
Ezinye zezinto ezibaluleke kakhulu ze-Polyvinyl Chloride (PVC) yilezi: Ukuminyana: I-PVC iminyene kakhulu uma iqhathaniswa namapulasitiki amaningi (amandla adonsela phansi athile azungeze u-1.4) Ezomnotho: I-PVC itholakala kalula futhi ishibhile. Ukuqina: I-PVC eqinile ilinganisa kahle ngobulukhuni nokuqina. Amandla: I-PVC eqinile inamandla amahle kakhulu okuqina. I-Polyvinyl Chloride iyimpahla ye-"thermoplastic" (ngokungafani ne-"thermoset"), ehlobene nendlela ipulasitiki esabela ngayo ekushiseni. Izinto ze-Thermoplastic ziba uketshezi lapho zincibilika (ibanga le-PVC eliphakathi kwezinga eliphansi kakhulu lika-100 degrees Celsius namanani aphezulu afana no-260 degrees Celsius kuye ngezithasiselo). Isibaluli esibalulekile esiwusizo mayelana ne-thermoplastics ukuthi ingashiswa ifike endaweni yokuncibilika, apholiswe, futhi iphinde ishisise futhi... -
Iyini i-caustic soda?
Ohambweni olumaphakathi oluya esitolo esikhulu, abathengi bangase baqoqe okokugeza, bathenge ibhodlela le-aspirin futhi babheke izihloko zakamuva zamaphephandaba nakomagazini. Uma uthi nhlá, kungase kungabonakali sengathi lezi zinto zinokufana okuningi. Kodwa-ke, ngayinye yazo, i-caustic soda idlala indima ebalulekile ohlwini lwezithako noma izinqubo zokukhiqiza. Iyini i-caustic soda? I-Caustic soda yi-chemical compound sodium hydroxide (NaOH). Le nhlanganisela iyi-alkali - uhlobo lwesisekelo olunganciphisa ama-asidi futhi ancibilike emanzini. Namuhla i-caustic soda ingakhiqizwa ngendlela yamapellets, ama-flakes, ama-powders, izixazululo nokunye. Isetshenziselwa ini i-caustic soda? I-Caustic soda isibe isithako esivamile ekukhiqizeni izinto eziningi zansuku zonke. Eyaziwa kakhulu ngokuthi i-lye, isetshenziswe ... -
Kungani i-Polypropylene isetshenziswa kaningi?
I-Polypropylene isetshenziswa kuzo zombili izinhlelo zasendlini nezimboni. Izakhiwo zayo eziyingqayizivele kanye nekhono lokuzivumelanisa namasu okwakha ahlukahlukene kuyenza igqame njengento ebaluleke kakhulu ekusetshenzisweni okubanzi. Esinye isici esibalulekile ikhono le-polypropylene ukusebenza njengokubili okokusebenza kwepulasitiki nanjengefayibha (njengalezo zikhwama zokukhangisa ezinikezwa emicimbini, izinhlanga, njll). Ikhono eliyingqayizivele le-polypropylene lokwenziwa ngezindlela ezihlukene futhi libe izinhlelo zokusebenza ezahlukene lasho ukuthi ngokushesha yaqala ukubekela inselele izinto eziningi ezindala ezihlukile, ikakhulukazi ezimbonini zokupakisha, zefayibha kanye nezimbaxa. Ukukhula kwayo kuye kwaqiniswa phakathi neminyaka edlule futhi isalokhu ibambe iqhaza elikhulu embonini yepulasitiki emhlabeni wonke. KwaCreative Mechanisms, si... -
Ayini ama-PVC granules?
I-PVC ingenye yepulasitiki esetshenziswa kakhulu emkhakheni wemboni. I-Plasticol, inkampani yase-Italy eseduze ne-Varese isikhiqize ama-PVC granules iminyaka engaphezu kwe-50 manje futhi ulwazi oluqoqwe phakathi neminyaka luvumela ibhizinisi ukuthi lithole izinga elijulile lolwazi kangangokuthi manje sesingakwazi ukulisebenzisa ukwanelisa wonke amaklayenti. ' izicelo ezihlinzeka ngemikhiqizo emisha nethembekile. Iqiniso lokuthi i-PVC isetshenziswa kabanzi ukukhiqiza izinto eziningi ezahlukahlukene likhombisa ukuthi izici zayo ezingaphakathi ziwusizo kakhulu futhi zikhethekile. Ake siqale ukukhuluma ngokuqina kwe-PVC: impahla iqinile kakhulu uma ihlanzekile kodwa iyashintshashintsha uma ihlanganiswe nezinye izinto. Lesi sici esihlukile senza i-PVC ilungele ukukhiqizwa kwemikhiqizo esetshenziswa emikhakheni ehlukene, kusukela esakhiweni esisodwa ...
