Izicelo eziphambili zePVC.

1. Iiprofayili zePVC

Iiprofayili zePVC kunye neeprofayili zezona ndawo zininzi zokusetyenziswa kwePVC eTshayina, zibalelwa malunga ne-25% yokusetyenziswa kwePVC iyonke. Ikakhulu zisetyenziselwa ukwenza iingcango kunye neefestile kunye nezixhobo zokonga amandla, kwaye umthamo wazo wesicelo usakhula kakhulu kwilizwe lonke. Kumazwe ahambele phambili kwezoqoqosho, izabelo zemarike yeengcango zeplastiki neefestile zikwakwinqanaba lokuqala, njenge-50% eJamani, i-56% eFransi, kunye ne-45% eUnited States.

 

2. Umbhobho wePVC

Phakathi kweemveliso ezininzi zePVC, iipayipi zePVC ziyindawo yesibini enkulu yokusetyenziswa, ibalwa malunga ne-20% yokusetyenziswa kwayo. E-China, imibhobho ye-PVC iphuhliswa kwangaphambili kunemibhobho ye-PE kunye nemibhobho ye-PP, eneentlobo ezininzi, ukusebenza okugqwesileyo kunye noluhlu olubanzi lwezicelo, ezithatha indawo ebalulekileyo kwimarike.

 

3. Ifilimu yePVC

Ukusetyenziswa kwe-PVC kwintsimi yefilimu ye-PVC ithatha indawo yesithathu, ibalwa malunga ne-10%. Emva kokuxuba kunye neeplastiki zePVC kunye nezongezo, sebenzisa i-calender ye-roll-roll okanye i-four-roll calender ukwenza ifilimu ecacileyo okanye enemibala kunye nobukhulu obucacileyo, kwaye uqhube ifilimu ngale ndlela ukuba ibe yifilimu yekhalenda. Iingxowa zokupakisha, i-raincoat, i-tablecloths, amakhethini, amathoyizi ane-inflatable, njl. Ifilimu ebanzi ecacileyo ingasetyenziselwa i-greenhouse, i-plastic greenhouse kunye nefilimu yeplastiki. Ifilimu eyoluliweyo ye-biaxially ingasetyenziselwa ukupakishwa kwe-shrink ngenxa yeempawu zayo zokunciphisa i-thermal.

 

4.PVC izinto ezinzima kunye nebhodi

Yongeza i-stabilizers, i-lubricants kunye ne-fillers kwi-PVC, kwaye emva kokuxuba, sebenzisa i-extruder ukukhupha imibhobho eqinile, imibhobho ekhethekileyo, kunye nemibhobho edibeneyo yobubanzi obuhlukeneyo, enokusetyenziswa njengemibhobho yogutyulo, imibhobho yamanzi okusela, iingcingo zocingo okanye i-stair handrails. . Amaphepha e-calender abekwe phezulu kwaye ashushu-acinezele ukwenza iipleyiti ezinzima zobunzima obahlukeneyo. Iipleyiti zinokusikwa zibe zimilo ezinqwenelekayo, kwaye emva koko zidityaniswe ngomoya oshushu zisebenzisa iintonga zokuwelda zePVC ukuze zenze iitanki zokugcina ezikwaziyo ukumelana neekhemikhali, imibhobho yomoya kunye nezikhongozeli.

 

5.PVC iimveliso ezithambileyo jikelele

I-extruders ingasetyenziselwa ukukhupha i-hoses, iintambo, iingcingo, njl. oomatshini bokubumba benaliti banokusetyenziselwa ukuthelekisa ukubumba okwahlukeneyo ukwenza iimbadada zeplastiki, iisole, izilayidi, iithoyi, iinxalenye zemoto, njl.

 

6. PVC ukupakisha imathiriyeli

Iimveliso zePVC zisetyenziswa ikakhulu kwizikhongozeli ezahlukahlukeneyo, iifilimu kunye namaphepha anzima okupakishwa. Izikhongozeli zePVC zisetyenziswa ikakhulu kwimveliso yamanzi amaminerali, iziselo, kunye neebhotile zokuthambisa, kwaye zikwasetyenziswa ekupakishweni kweeoyile ezisulungekileyo. Ifilimu ye-PVC ingasetyenziselwa i-coextrusion kunye nezinye iipolymers ukuvelisa i-laminates ephantsi kwexabiso eliphantsi, kunye neemveliso ezicacileyo ezineempawu ezintle zomqobo. Ifilim yePVC ikwasetyenziswa ekusoluleni okanye ekusongelweni okushwabeneyo koomatrasi, ilaphu, iithoyi kunye nempahla yamashishini.

 

7. PVC siding kunye nomgangatho

I-PVC siding isetyenziswa ikakhulu ukutshintsha i-aluminiyam siding. Ngaphandle kwenxalenye ye-polyvinyl chloride resin, ezinye iinqununu ze-polyvinyl chloride floor tiles ziyizinto ezihlaziyiweyo, i-adhesives, fillers kunye nezinye izinto, ezisetyenziswa kakhulu emhlabeni wezakhiwo ze-airport terminal kunye nomhlaba onzima kwezinye iindawo.

 

8. Iimpahla zabathengi zePolyvinyl chloride

Ingxowa yemithwalo yimveliso yendabuko eyenziwe nge-polyvinyl chloride. I-Polyvinyl chloride isetyenziselwa ukwenza iindidi ezahlukeneyo zokulinganisa iingxowa zemithwalo kunye neemveliso zemidlalo ezifana ne-basketball, ibhola ekhatywayo kunye nombhoxo. Ingasetyenziselwa ukwenza amabhande eeyunifomu kunye nezixhobo ezikhethekileyo zokukhusela. Amalaphu e-polyvinyl chloride empahla aqhele ukufunxa amalaphu (akukho ngubo efunekayo), njengeekepesi zemvula, ibhulukhwe yomntwana, iibhatyi zesikhumba ezifanisiweyo kunye neebhutsi zemvula ezahlukeneyo. I-PVC isetyenziswa kwiimveliso ezininzi zemidlalo kunye nezolonwabo, ezifana namathoyizi, iirekhodi kunye neemveliso zemidlalo. Izinto zokudlala zePVC kunye neemveliso zemidlalo zinezinga elikhulu lokukhula, kwaye zineenzuzo ngenxa yeendleko zazo eziphantsi zemveliso kunye nokubumba okulula.

 

9. Iimveliso ezigqunywe ngePVC

Isikhumba sokwenziwa esixhaswayo senziwe ngokufaka intlama yePVC kwilaphu okanye ephepheni, emva koko iplastiki ifakwe ngaphezu kwe-100°C. Ingenziwa kwakhona ngokuqengqeleka i-PVC kunye nezongezo kwifilimu kuqala, kwaye emva koko uyicinezele nge-substrate. Isikhumba sokwenziwa ngaphandle kokuxhaswa ngokuthe ngqo sifakwe kwi-calender kwi-soft sheet yobunzima obuthile yi-calender, kwaye emva koko icinezelwe ngepateni. ngethwathwa, esetyenziswa njengezinto zomgangatho wezakhiwo.

 

10.PVC iimveliso ugwebu

Xa i-PVC ethambileyo ixovulwa, umlinganiselo ofanelekileyo we-arhente yogwebu uyongezwa ukwenza i-sheet, efakwe ugwebu kwaye yenziwe ibe yiplastiki yogwebu, enokusetyenziswa njenge-slippers yogwebu, iimbadada, i-insoles, kunye nezixhobo zokupakisha zokupakisha. Isenokusetyenziselwa ukwenza amaphepha e-PVC anegwebu aphantsi kunye nezinto ezineprofayili esekelwe kwi-extruders, enokusetyenziswa endaweni yomthi. Luhlobo olutsha lwemathiriyeli yokwakha.

 

11.PVC sheet transparent

Yongeza isilungisi sempembelelo kunye ne-organotin stabilizer kwi-PVC, kwaye ube kwiphepha elicacileyo emva kokuxuba, iplastiki kunye ne-calendering. Ingenziwa kwizikhongozeli ezibonakala zibhityile ezinodonga okanye zisetyenziswe kwi-vacuum blister package nge-thermoforming. Yimpahla egqwesileyo yokupakisha kunye nempahla yokuhlobisa.

 

12. Okunye

Iingcango kunye neefestile zidityaniswe ngemathiriyeli eqinile. Kwamanye amazwe, uye wathatha umnyango kunye nefestile yemarike kunye neengcango zokhuni kunye neefestile, iifestile ze-aluminium, njl.; ukuxelisa izinto zokhuni, izinto zokwakha ezithatha indawo yentsimbi (emantla, elwandle); izitya ezingenanto.
