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 ... -
I-biodegradable glitter ingase iguqule imboni yezimonyo.
Ukuphila kugcwele izinto ezipakishwayo ezicwebezelayo, amabhodlela ezimonyo, izitsha zezithelo nokunye, kodwa eziningi zazo zenziwe ngezinto ezinobuthi nezingalawuleki ezifaka isandla ekungcoleni kwepulasitiki. Muva nje, abacwaningi eNyuvesi yaseCambridge e-UK bathole indlela yokudala i-glitter eqhubekayo, engeyona enobuthi ne-biodegradable kusuka ku-cellulose, isakhiwo esiyinhloko sezindonga zamaseli zezitshalo, izithelo nemifino. Amaphepha ahlobene ashicilelwe kumagazini we-Nature Materials ngomhla ka-11. Yenziwe ngama-nanocrystals e-cellulose, le glitter isebenzisa umbala wesakhiwo ukuze iguqule ukukhanya ukuze ikhiqize imibala egqamile. Ngokwemvelo, isibonelo, ukukhanya kwamaphiko ovemvane nezimpaphe zepikoko kuwubuciko bombala wesakhiwo, ongeke uphele ngemva kwekhulu leminyaka. Ngokusebenzisa amasu okuzihlanganisa, i-cellulose ingakhiqiza ... -
Iyini i-Polyvinyl chloride (PVC) yokunamathisela i-Resin?
I-Polyvinyl chloride (PVC) inamathisela i-Resin , njengoba negama lisho, ukuthi le resin isetshenziswa kakhulu ekunamathiseleni. Abantu bavame ukusebenzisa lolu hlobo lokunamathisela njenge-plastisol, okuwuketshezi oluyingqayizivele lwe-PVC yepulasitiki esimweni sayo esingacutshungulwanga. . Ama-resin okunamathisela avame ukulungiswa nge-emulsion kanye nezindlela zokumisa ezincane. I-Polyvinyl chloride paste resin inosayizi wezinhlayiyana ezinhle, futhi ukuthungwa kwayo kufana ne-talc, nokunganyakazi. I-polyvinyl chloride paste resin ixutshwa ne-Plasticizer bese inyakaziswa ukuze yakhe ukumiswa okuzinzile, okube sekwenziwa unamathisele we-PVC, noma i-PVC plastisol, i-PVC sol, futhi kungaleli fomu lapho abantu basetshenziselwa ukucubungula Imikhiqizo yokugcina. Enqubweni yokwenza unamathisele, ama-fillers ahlukahlukene, ama-diluents, ama-heat stabilizers, ama-foaming agents kanye neziqinisi zokukhanya zengezwa ngokusho ... -
Yini i-PP Films?
I-PROPERTIES I-Polypropylene noma i-PP iyi-thermoplastic ebiza kancane yokucaca okuphezulu, i-gloss ephezulu namandla amahle okuqina. Inephuzu lokuncibilika eliphakeme kune-PE, okwenza ifanelekele izinhlelo zokusebenza ezidinga ukuvalwa kwembewu emazingeni okushisa aphezulu. Iphinde ibe nenkungu encane kanye nokucwebezela okuphezulu. Ngokuvamile, izici zokuvala ukushisa kwe-PP azilungile njengalezo ze-LDPE. I-LDPE futhi inamandla angcono okudabula kanye nokumelana nomthelela ophansi wokushisa. I-PP ingenziwa nge-metallized okuholela ekuthuthukisweni kwezakhiwo zokuvimbela igesi ezisetshenziswayo ezifunayo lapho impilo yeshalofu yomkhiqizo ende ibalulekile. Amafilimu e-PP afaneleka kahle uhla olubanzi lwezinhlelo zokusebenza zezimboni, abathengi, nezimoto. I-PP igaywa kabusha ngokuphelele futhi ingacutshungulwa kalula kweminye imikhiqizo eminingi yezinhlelo zokusebenza eziningi ezahlukahlukene. Nokho, unl... -
yini i-PVC compound?
Izinhlanganisela ze-PVC zisekelwe ekuhlanganiseni kwe-PVC polymer RESIN kanye nezithasiselo ezinikeza ukwakheka okudingekayo ukuze kusetshenziswe ekugcineni (Amapayipi noma Amaphrofayili Aqinile noma Amaphrofayili Aguquguqukayo noma AmaSpredishithi). I-compound yakhiwa ngokuxubana ngokuseduze ndawonye izithako, ezibuye ziguqulelwe ku-athikili ethi "gelled" ngaphansi kwethonya lokushisa namandla okugunda. Kuye ngohlobo lwe-PVC nezithasiselo, i-compound ngaphambi kwe-gelation ingaba i-powder egelezayo (eyaziwa ngokuthi ingxube eyomile) noma i-liquid ngendlela yokunamathisela noma isisombululo. Izinhlanganisela ze-PVC uma zakhiwe, kusetshenziswa ama-plasticizers, zibe izinto eziguquguqukayo, ngokuvamile ezibizwa nge-PVC-P. Ama-PVC Compounds uma enziwa ngaphandle kwe-plasticizer yezinhlelo zokusebenza eziqinile aqokwa i-PVC-U. I-PVC Compounding ingafingqwa kanje: I-PVC eqinile dr... -
Umehluko Phakathi kwe-BOPP, OPP kanye ne-PP Bags.
Imboni yokudla isebenzisa kakhulu ukupakishwa kwepulasitiki ye-BOPP. Izikhwama ze-BOPP kulula ukuziphrinta, ukugqokwa kanye ne-laminate okuzenza zifanelekele ukupakisha imikhiqizo efana nemikhiqizo emisha, ama-confectionary kanye nokudla okulula. Kanye nezikhwama ze-BOPP, OPP, ne-PP nazo zisetshenziselwa ukupakisha. I-Polypropylene iyi-polymer evamile phakathi kwezintathu ezisetshenziselwa ukukhiqiza izikhwama. I-OPP imele i-Oriented Polypropylene, i-BOPP imele i-Biaxially Oriented Polypropylene kanti i-PP imele i-Polypropylene. Bobathathu bayehluka ngesitayela sabo sokwakha. I-polypropylene eyaziwa nangokuthi i-polypropene iyi-polymer ye-thermoplastic semi-crystalline. Iqinile, inamandla futhi inokumelana nomthelela omkhulu. Izikhwama ze-standup, izikhwama ze-spout kanye nezikhwama ze-ziplock zenziwe nge-polypropylene. Kunzima kakhulu ukuhlukanisa phakathi kwe-OPP, BOPP kanye ne-PP plas... -
Ucwaningo Lokusebenza Lokugxilisa Ukukhanya (PLA) ku-LED Lighting System.
Ososayensi abavela eJalimane nase-Netherlands bacwaninga ngezinto ezintsha ze-PLA ezihambisana nemvelo. Inhloso ukuthuthukisa izinto ezisimeme zezinhlelo zokusebenza ze-optical ezifana nezibani zangaphambili zezimoto, amalensi, amapulasitiki akhanyayo noma iziqondiso ezikhanyayo. Okwamanje, le mikhiqizo ngokuvamile yenziwe nge-polycarbonate noma i-PMMA. Ososayensi bafuna ukuthola ipulasitiki esekwe ku-bio yokwenza izibani zemoto. Kuvela ukuthi i-polylactic acid iyinto efanelekile yekhandidethi. Ngale ndlela, ososayensi baye baxazulula izinkinga eziningana ezibhekene namapulasitiki endabuko: okokuqala, ukunaka izinsiza ezivuselelekayo kunganciphisa ngokuphumelelayo ingcindezi ebangelwa uwoyela ongahluziwe embonini yepulasitiki; okwesibili, kunganciphisa ukukhishwa kwesikhutha; okwesithathu, lokhu Kubandakanya ukucutshungulwa kwayo yonke impilo yezinto ezibonakalayo c... -
Isingeniso mayelana ne-Haiwan PVC Resin.
Manje ngizokwethula okwengeziwe ngomkhiqizo omkhulu wase-China we-Ethylene PVC: i-Qingdao Haiwan Chemical Co., Ltd, etholakala esifundazweni saseShandong eMpumalanga China, ibanga lamahora angu-1.5 ngendiza esuka e-Shanghai. IShandong iyidolobha elibalulekile elimaphakathi ogwini lwaseChina, indawo yokuphumula esogwini kanye nedolobha labavakashi, kanye nedolobha eliyitheku lamazwe ngamazwe.
