Iyini ifilimu ye-Biaxially Oriented Polypropylene Overwrap?
Ifilimu ye-Biaxially oriented polypropylene (BOPP) iwuhlobo lwefilimu yokupakisha eguquguqukayo.Ifilimu ye-polypropylene overwrap eyenziwe nge-Biaxially yeluliwe emshinini naseziqondisweni eziphambene.Lokhu kubangela umumo wochungechunge lwamangqamuzana kuzo zombili izinkomba.Lolu hlobo lwefilimu yokupakisha eguquguqukayo lwenziwa ngenqubo yokukhiqiza amashubhu.Ibhamuza lefilimu elimise okweshubhu liyafuthwa bese lishiselwa lize lifike endaweni yalo yokuthamba (lokhu kwehlukile endaweni yokuncibilika) futhi yelulelwa ngemishini.Ifilimu inweba phakathi kuka-300% - 400%.Kungenjalo, ifilimu inganwetshwa ngenqubo eyaziwa ngokuthi ukukhiqizwa kwefilimu ye-tent-frame.Ngale ndlela, ama-polymers adluliselwa ku-cast cast roll epholile (owaziwa nangokuthi i-base sheet) futhi adwetshwe ngendlela yomshini.Ifilimu ye-Tenter-frame isenza... -
Umthamo wokuthekelisa ukhule kakhulu kusukela ngoJanuwari kuya kuFebhuwari 2023.
Ngokwezibalo zedatha yamasiko: kusukela ngoJanuwari kuya kuFebruwari 2023, ivolumu yasekhaya yokuthekelisa ye-PE ingamathani angu-112,400, okuhlanganisa amathani angu-36,400 e-HDPE, amathani angu-56,900 e-LDPE, kanye namathani angu-19,100 e-LLDPE.Kusukela ngoJanuwari kuya kuFebhuwari, umthamo wangaphakathi we-PE ukhuphuke ngamathani angama-59,500 uma kuqhathaniswa nesikhathi esifanayo ngo-2022, okukhuphuke ngo-112.48%.Kusuka eshadini elingenhla, singabona ukuthi ivolumu yokuthumela ngaphandle kusukela ngoJanuwari kuya kuFebruwari ikhuphuke kakhulu uma iqhathaniswa nesikhathi esifanayo ngo-2022. Ngokwezinyanga, umthamo wokuthekelisa ngo-January 2023 ukhuphuke ngamathani angu-16,600 uma kuqhathaniswa nesikhathi esifanayo ngonyaka odlule, futhi umthamo wokuthunyelwa kwempahla kwamanye amazwe ngoFebhuwari ukhuphuke ngamathani angu-40,900 uma kuqhathaniswa nesikhathi esifanayo ngonyaka odlule;ngokuya ngezinhlobonhlobo, umthamo wokuthekelisa we-LDPE (Januwari-Februwari) wawungamathani angama-36,400 , a ye... -
Izinhlelo zokusebenza eziyinhloko ze-PVC.
1. Amaphrofayili e-PVC I-PVC Amaphrofayili kanye namaphrofayili yizindawo ezinkulu kakhulu zokusetshenziswa kwe-PVC e-China, okubalelwa cishe ku-25% wengqikithi yokusetshenziswa kwe-PVC.Ngokuyinhloko zisetshenziselwa ukwenza iminyango namafasitela nezinto zokonga amandla, futhi umthamo wazo wokufaka isicelo usakhula kakhulu ezweni lonke.Emazweni athuthukile, ingxenye yemakethe yezicabha namafasitela epulasitiki nayo ihamba phambili, njengamaphesenti angama-50 eJalimane, angama-56% eFrance, nama-45% e-United States.2.

Izinhlobo ze-polypropylene .
Ama-molecule e-polypropylene aqukethe amaqembu e-methyl, angahlukaniswa abe yi-isotactic polypropylene, atactic polypropylene kanye ne-sydiotactic polypropylene ngokuvumelana nokuhlelwa kwamaqembu e-methyl.Lapho amaqembu e-methyl ehlelwa ohlangothini olufanayo lweketango eliyinhloko, libizwa ngokuthi i-isotactic polypropylene;uma amaqembu e-methyl esatshalaliswa ngokungahleliwe ezinhlangothini zombili zeketango eliyinhloko, kubizwa ngokuthi i-atactic polypropylene;lapho amaqembu e-methyl ehlelwa ngokushintshana ezinhlangothini zombili zeketango eliyinhloko, ibizwa ngokuthi i-sydiotactic.i-polypropylene.Ekukhiqizweni okujwayelekile kwe-polypropylene resin, okuqukethwe kwesakhiwo se-isotactic (okubizwa ngokuthi isotacticity) cishe ku-95%, kanti enye i-atactic noma i-sydiotactic polypropylene.I-polypropylene resin okwamanje ekhiqizwa eChina ihlukaniswa ngokusho ... -
Ukusetshenziswa kwe-paste pvc resin.
Kulinganiselwa ukuthi ngo-2000, ukusetshenziswa okuphelele kwemakethe ye-PVC yokunamathisela resin yomhlaba wonke kwakulinganiselwa ku-1.66 million t/a.E-China, i-PVC yokunamathisela i-resin ngokuyinhloko inalezi zicelo ezilandelayo: Imboni yesikhumba yokwenziwa: ukunikezwa kwemakethe iyonke kanye nebhalansi yokufunwa.Kodwa-ke, okuthintwe ukuthuthukiswa kwesikhumba se-PU, isidingo sesikhumba sokwenziwa e-Wenzhou nakwezinye izindawo ezinkulu zokusetshenziswa kwe-resin yokunamathisela singaphansi kwemikhawulo ethile.Ukuncintisana phakathi kwesikhumba se-PU nesikhumba sokwenziwa kushubile.Imboni yesikhumba yaphansi: Ithintwa ukuncipha kwesidingo sesikhumba esiphansi, isidingo se-paste resin kule mboni sehle unyaka nonyaka eminyakeni yamuva.Imboni yempahla yamagilavu: isidingo sikhulu uma kuqhathaniswa, ikakhulukazi emazweni angaphandle, okungesokucubungula komlingani ohlinzekiwe... -
Ukusetshenziswa kwe-caustic soda kuhilela izinkambu eziningi.
I-Caustic soda ingahlukaniswa ibe yi-flake soda, i-granular soda ne-soda eqinile ngokuvumelana nefomu layo.Ukusetshenziswa kwe-caustic soda kuhilela izinkambu eziningi, okulandelayo yisingeniso esinemininingwane kuwe: 1. I-petroleum ecwengisisiwe.Ngemuva kokugezwa nge-sulfuric acid, imikhiqizo ye-petroleum isaqukethe izinto ezine-acidic, okufanele zigezwe ngesisombululo se-sodium hydroxide bese igezwa ngamanzi ukuze kutholwe imikhiqizo ecolisisiwe.2.ukuphrinta nokudaya Okusetshenziswa kakhulu kumadayi e-indigo kanye nodayi bequinone.Enqubweni yokudaya odayi be-vat, isisombululo se-caustic soda kanye ne-sodium hydrosulfite kufanele isetshenziselwe ukuwanciphisa ku-leuco acid, bese i-oxidized esimweni sokuqala esingancibiliki ngama-oxidants ngemva kokudaya.Ngemuva kokuthi indwangu kakotini iphathwe ngesisombululo se-caustic soda, i-wax, amafutha, isitashi nezinye izinto ... -
Ukubuyiselwa kwesidingo se-PVC yomhlaba wonke kuncike eChina.
Kungena ngo-2023, ngenxa yesidingo esivilaphayo ezifundeni ezahlukahlukene, imakethe yomhlaba wonke ye-polyvinyl chloride (PVC) isabhekene nokungaqiniseki.Esikhathini esiningi se-2022, amanani entengo e-PVC e-Asia nase-United States abonise ukwehla okukhulu futhi aphuma phansi ngaphambi kokungena ku-2023. Ukungena ku-2023, phakathi kwezifunda ezihlukahlukene, ngemva kokuba i-China ilungise izinqubomgomo zayo zokuvimbela nokulawula ubhubhane, imakethe ilindele ukuphendula;i-United States ingase iqhubeke inyuse izilinganiso zenzalo ukuze ilwe nokwehla kwamandla emali futhi inqande isidingo sasekhaya se-PVC e-United States.I-Asia, eholwa yi-China, ne-United States ikhulise ukuthunyelwa kwe-PVC phakathi kwesidingo esibuthakathaka somhlaba wonke.Ngokuqondene neYurophu, lesi sifunda sisazobhekana nenkinga yamanani aphezulu kagesi kanye nokwehla kwamandla emali, futhi cishe ngeke kube khona ukusimama okusimeme emalini yenzuzo yezimboni.... -
