Iyini ishidi eliqinile le-PVC?

 

Igama eliphelele lebhodi eliqinile le-PVC yi-Polyvinyl Chloride Rigid Sheet. Isebenzisa izinto ezingezona ezi-amorphous njengezinto zokusetshenziswa, inezakhiwo zokulwa nokubola, ukulwa ne-asidi kanye nokunciphisa. Amabhodi aqinile e-PVC nawo anamandla aphezulu kanye nokuqina okuhle kakhulu, awashisi futhi amelana nokugqwala okubangelwa ukushintsha kwesimo sezulu. Amabhodi aqinile e-PVC avamile afaka ibhodi le-PVC elibonakalayo, ibhodi le-PVC elimhlophe, ibhodi le-PVC elimnyama, ibhodi le-PVC elimpunga, ibhodi le-PVC elimpunga, njll.

 

 

Yiziphi izinzuzo zeshidi le-PVC?

 

Ishidi le-PVC aligcini nje ngokuba nezinzuzo eziningi njengokumelana nokugqwala, ukuvimbela ilangabi, ukuvikela ukushisa, kanye nokumelana nokushiswa kwe-oxidation kodwa futhi ngenxa yokusebenziseka kahle kanye nezindleko eziphansi zokukhiqiza, ishidi le-PVC ligcine inani eliphezulu lokuthengisa emakethe yeshidi lepulasitiki. Ngenxa yokusetshenziswa kwalo okubanzi kanye namanani angabizi, amabhodi aqinile e-PVC abelokhu ethatha ingxenye enkulu yemakethe yeshidi lepulasitiki. Njengamanje, ubuchwepheshe bocwaningo nokuthuthukiswa kweshidi le-PVC eShayina bufinyelele ezingeni elithuthukile lomhlaba wonke.

 

Yiziphi izigaba zeshidi/ifilimu eqinile ye-PVC?

 

Kunezinhlobo eziningi zamashidi e-PVC, kunezinhlobo ezahlukene zamashidi e-PVC, njengamashidi e-PVC aqinile, amashidi e-PVC amancane, amashidi e-PVC abonakalayo, amashidi e-PVC amnyama, amashidi e-PVC amhlophe, amashidi e-PVC acwebezelayo, amashidi e-PVC acwebezelayo.

 

 

Yiziphi izinkinga ngeshidi le-PVC?

 

Ama-plasticizer kumashidi e-PVC ansuku zonke asebenzisa kakhulu i-dibutyl terephthalate kanye ne-dioctyl phthalate. Lawa makhemikhali anobuthi, njengoba kunjalo ne-lead stearate (i-antioxidant ye-PVC). I-lead iyaphuma lapho amashidi e-PVC aqukethe usawoti we-lead antioxidants ehlangana ne-ethanol, i-ether, nezinye izinyibilikisi. Amashidi e-PVC aqukethe i-lead asetshenziselwa ukupakisha ukudla. Lapho ehlangana nezinti zenhlama ethosiwe, amakhekhe athosiwe, inhlanzi ethosiwe, imikhiqizo yenyama ephekiwe, amakhekhe, kanye nokudla okulula, ama-molecule e-lead azosakazeka emafutheni, ngakho-ke izikhwama zepulasitiki ze-PVC azikwazi ukusetshenziselwa ukuhlanganisa ukudla. Ikakhulukazi ukudla okunamafutha. Ngaphezu kwalokho, imikhiqizo yepulasitiki ye-polyvinyl chloride izobola kancane kancane igesi ye-hydrogen chloride ekushiseni okuphezulu, cishe cishe ngo-50 °C, okuyingozi emzimbeni womuntu. Ngakho-ke, imikhiqizo ye-PVC ayifaneleki ukupakisha ukudla.

 

Kuyini ukusetshenziswa kweshidi eliqinile le-PVC elihleliwe?

 

Ukusetshenziswa kweshidi eliqinile le-PVC elihleliwe nakho kubanzi kakhulu, okusetshenziselwa kakhulu ukwenza ifilimu yesihlahla sikaKhisimusi ye-PVC, ucingo lokwenza ifilimu eluhlaza ye-PVC, isembozo sokubopha se-PVC, ikhadi lebhizinisi le-PVC, ibhokisi lokugoqa le-PVC, ucezu lophahla lwe-PVC, izinto zokudlala zekhadi le-PVC, ishidi eliqinile le-PVC blister, njll.

 

 

Yibuphi ubukhulu obuvame kakhulu beshidi le-PVC elihlanganisiwe?

 

Kuya ngesidingo sakho, singenza kusukela ku-0.05mm kuya ku-1.2mm.

 

Uyini umehluko phakathi kwezinqubo zokucubungula kanye nezinqubo zokukhipha?

Nakuba inqubo yokucubungula ikhalenda ingakhiqiza imikhiqizo engcono kunenqubo yokukhipha, ayisebenzi futhi ukulahlekelwa kukhulu kakhulu uma imininingwane iphezulu kakhulu noma imininingwane iphansi kakhulu.
