I-PVC Resin SG5, Ilungele Ukuthunyelwa ~

Isicelo

1. Amaphrofayili e-PVC

Amaphrofayili namaphrofayili yizindawo ezisetshenziswa kakhulu yi-PVC ezweni lami, abiza cishe u-25% wenani eliphelele lokusetshenziswa kwe-PVC. Asetshenziswa kakhulu ekwenzeni iminyango namafasitela nezinto zokonga amandla, futhi umthamo wokusetshenziswa kwawo usakhula kakhulu ezweni lonke. Emazweni athuthukile, isabelo semakethe seminyango namafasitela epulasitiki naso siphezulu kakhulu, njengo-50% eJalimane, u-56% eFrance, kanye no-45% e-United States.

2. Amapayipi e-PVC

Phakathi kwemikhiqizo eminingi ye-PVC, amapayipi e-PVC ayindawo yesibili ngobukhulu yokusetshenziswa, ebalelwa cishe ku-20% wokusetshenziswa kwawo. Ezweni lakithi, amapayipi e-PVC athuthukiswa ngaphambi kwamapayipi e-PE namapayipi e-PP, anezinhlobo eziningi, ukusebenza okuhle kakhulu, kanye nokusetshenziswa okubanzi, okuthatha isikhundla esibalulekile emakethe.

3. Ifilimu ye-PVC

Ukusetshenziswa kwe-PVC ensimini yefilimu ye-PVC kusendaweni yesithathu, okubalwa cishe yi-10%. Ngemva kokuba i-PVC ixutshwe nezithasiselo futhi yenziwe ipulasitiki, ikhalenda enama-roll amathathu noma amane isetshenziswa ukwenza ifilimu ecacile noma enemibala enobukhulu obuthile. Ifilimu icutshungulwa ngale ndlela ukuze ibe ifilimu ehleliwe. Ingacutshungulwa futhi ibe yizikhwama zokupakisha, amajazi emvula, izindwangu zamatafula, amakhethini, amathoyizi afuthwayo, njll. ngokusika nokuvala ukushisa. Amafilimu abanzi acacile angasetshenziswa ezindaweni zokugcina izithombo, izindawo zokugcina izithombo zepulasitiki kanye namafilimu aphansi. Ifilimu enwetshiwe kabili ingasetshenziswa ekupakisheni okuncishisiwe ngenxa yezici zayo zokuncipha kokushisa.

4. Izinto eziqinile ze-PVC namashidi

Faka iziqinisi, izinto zokugcoba kanye nezigcwalisi ku-PVC. Ngemva kokuxuba, i-extruder ingakhipha ama-caliber ahlukahlukene amapayipi aqinile, amapayipi anomumo okhethekile, kanye namapayipi ahlanganisiwe, asetshenziswa njengamapayipi okuhambisa indle, amapayipi amanzi okuphuza, izimbobo zocingo noma izibambo zezitebhisi. Amashidi asongiwe ayagoqeka futhi acindezelwe ngokushisa ukuze kwenziwe amashidi aqinile anobukhulu obuhlukahlukene. Amashidi angasikwa abe ngesimo esidingekayo, bese kusetshenziselwa izinduku zokushisela ze-PVC ukushisela amathangi okugcina ahlukahlukene angamelani namakhemikhali, amapayipi omoya kanye nezitsha ngomoya oshisayo.

5. Imikhiqizo ethambile ejwayelekile ye-PVC

Ukusebenzisa i-extruder, ingakhishwa iye kumapayipi, izintambo, izintambo, njll.; kusetshenziswa umshini wokubumba umjovo onezinhlobo ezahlukene zesikhunta, kungenziwa ngayo amasandali epulasitiki, amasoli, amaslipper, amathoyizi, izingxenye zezimoto, njll.

6. Izinto zokupakisha ze-polyvinyl chloride

Imikhiqizo ye-polyvinyl chloride isetshenziswa kakhulu ekupakisheni izitsha ezahlukahlukene, amafilimu namashidi aqinile. Izitsha ze-PVC zisetshenziselwa kakhulu ukukhiqiza amanzi amaminerali, iziphuzo, namabhodlela ezimonyo, futhi zisetshenziselwa nokupakisha uwoyela ocolisisiwe. Ifilimu ye-PVC ingasetshenziswa ukukhipha kanye namanye ama-polymer ukukhiqiza imikhiqizo eshibhile ene-laminated, kanye nemikhiqizo esobala enezakhiwo ezinhle zokuvimbela. Ifilimu ye-PVC ingasetshenziswa futhi ekupakisheni okwelula noma ukwehlisa ukushisa, futhi isetshenziselwa ukupakisha omatilasi, indwangu, amathoyizi, kanye nezimpahla zezimboni.

7. Uphahla lwe-PVC kanye nophahla

I-PVC siding isetshenziswa kakhulu ukufaka esikhundleni se-aluminium siding. Ngaphezu kwengxenye ye-resin ye-PVC, izingxenye ezisele zamathayela aphansi e-PVC ziyizinto eziphinde zasetshenziswa, izinamathiseli, izigcwalisi, nezinye izingxenye. Zisetshenziswa kakhulu emhlabathini oqinile wezindawo zokugcina izindiza nakwezinye izindawo.

8. Izimpahla zansuku zonke ze-PVC

Izikhwama zemithwalo ziyimikhiqizo yendabuko eyenziwe nge-PVC. I-PVC isetshenziselwa ukwenza izikhumba zokulingisa ezahlukahlukene zezikhwama zemithwalo, imikhiqizo yezemidlalo, njenge-basketball, ibhola lezinyawo, kanye ne-rugby. Ingasetshenziswa futhi ukwenza amabhande eyunifomu kanye nemishini ekhethekile yokuzivikela. Izindwangu ze-PVC zezingubo ngokuvamile ziyizindwangu ezimunca (akudingeki ukugqoka), njengezingubo zemvula, amabhulukwe ezingane, amajakethi esikhumba okulingisa, kanye namabhuzu emvula ahlukahlukene. I-Polyvinyl chloride isetshenziswa emikhiqizweni eminingi yezemidlalo nokuzijabulisa, njengezinto zokudlala, amarekhodi kanye nemishini yezemidlalo. Amathoyizi e-Polyvinyl chloride kanye nemishini yezemidlalo anesilinganiso esikhulu sokukhula, futhi anenzuzo ngenxa yezindleko zawo eziphansi zokukhiqiza kanye nokubumba okulula.

9. Imikhiqizo embozwe nge-PVC

Isikhumba sokwenziwa esine-backback senziwa ngokufaka i-PVC paste endwangwini noma ephepheni, bese siyifaka ipulasitiki ngaphezu kuka-100°C. Singenziwa nangokufaka i-PVC kanye nezithasiselo kuqala efilimini, bese siyicindezela nge-backback. Isikhumba sokwenziwa esingena-backback sihlanganiswa ngqo ephepheni elithambile elinobukhulu obuthile yi-calender, bese sicindezelwa ngephethini. Isikhumba sokwenziwa singasetshenziswa ukwenza amasudikesi, izikhwama, izembozo zezincwadi, amasofa kanye nemicamelo yezihlalo zezimoto, njll., kanye nesikhumba saphansi, esisetshenziswa njengezinto zokwakha phansi ezakhiweni.

10. Imikhiqizo ye-PVC foam

Uma i-PVC ethambile ixutshwa, inani elifanele le-ejenti yokwenza igwebu liyangezwa ukwenza ishidi, elifakwa igwebu libe yipulasitiki yegwebu, elingasetshenziswa njengezicathulo zegwebu, izimbadada, ama-insoles, kanye nezinto zokupakisha ezivikela ukushaqeka. Lingenziwa futhi libe amashidi namaphrofayili e-PVC aqinile anegwebu eliphansi ngokusekelwe ku-extruder, engathatha indawo yokhuni futhi iwuhlobo olusha lwezinto zokwakha.

11. Ishidi le-PVC elibonakalayo

I-PVC yengezwa nge-impact modifier kanye ne-organic tin stabilizer, futhi iba yishidi elibonakalayo ngemva kokuxuba, ukwenza ipulasitiki kanye nokufaka ikhalenda. Ingenziwa ibe yizitsha ezikhanyayo ezinezindonga ezincane noma isetshenziselwe ukupakisha ama-blister nge-thermoforming, futhi iyinto enhle kakhulu yokupakisha kanye nezinto zokuhlobisa.

12. Abanye

Iminyango namafasitela ahlanganiswa ngezinto eziqinile ezinomumo okhethekile. Kwamanye amazwe, agcwele imakethe yeminyango namafasitela kanye neminyango namafasitela okhuni, amafasitela e-aluminium, njll.; izinto zokhuni mbumbulu, izinto zokwakha ezithatha indawo yensimbi (enyakatho, ogwini lolwandle); izitsha ezingenalutho.
