yini i-PVC eqinile?,
i-PVC extrusion eqinile, i-UPVC,
I-PVC eqinile (eyaziwa nangokuthii-UPVC) iyipolymer yesithathu ekhiqizwa kakhulu.Ngokuya nge-extrusions yepulasitiki, i-PVC iyipulasitiki eqinile evame ukukhishwa.Ibiza kancane, inezinto ezigaywa kabusha futhi iguquguquka ukuze isetshenziswe ngaphakathi nangaphandle.Lokhu kwenzai-PVC extrusion eqinilesa choice popular anhlobonhlobo izicelo.I-UPVC imele i-PVC engaxutshiwe futhi impahla ibonakala ngokuqina kwayo namandla.Futhi iyipulasitiki evumelana nezimo ngokwedlulele, elungele ukusetshenziswa okuningi
Izakhiwo ze-PVC eziqinile
I-PVC iyi-polymer eqinile engathuthukiswa ngokwengeziwe kusetshenziswa izilungisi zomthelela.Ama-extrusions e-PVC aqinile anokuqina kwamakhemikhali aqinile.Lokhu kusho ukuthi amashubhu e-PVC aqinile angashiselwa kalula, anamathiselwe futhi ahlanganiswe wona ngokwawo - alungele amalunga amapayipi.Ukumelana kwayo nokugqwala kwenza amaphrofayili e-PVC aqinile, izigaba nezinsini zilungele izindawo zangaphandle.I-PVC iphinde ibe nezakhiwo ezinhle zokuvikela ukusetshenziswa kwamandla kagesi aphansi.Ngenxa yezinzuzo zayo eziningi,i-PVC extrusion eqiniles kanye namashubhu e-PVC aqinile asetshenziswe ngempumelelo kokubili ezindaweni zasendlini nangaphandle.
Ama-extrusions e-PVC aqinile asetshenziswa
I-PVC eqinile isetshenziswa kabanzi ekwakhiweni kwamapayipi amanzi kanye nemfucuza, ama-conservatories, ama-gutters, i-cladding, ukuvikelwa kwezindonga nezicabha kanye namafreyimu amafasitela ngenxa yezindawo zayo ezinhle kakhulu ezishisayo nokuzinza.Ezicelweni zezokuthutha i-PVC isetshenziswa ngaphandle emizimbeni yezimoto, amakharavani kanye nezikebhe, nangaphakathi ekwakheni ubuhle obuthokozisayo, njengoba itholakala ngemibala eminingi kanye nokuqedwa kwendawo.Ezimbonini zomkhakha wezokuthengisa, ama-racks okugcina, amapheshana amathikithi kanye nama-poster grippers konke kukhiqizwa ku-PVC eqinile ekhishwe.
Ifaka i-thermo plasticity, engancibiliki emanzini, kuphethiloli notshwala, evuvukele noma encibilike ibe yi-ether, i-ketone, i-chlorinated aliphatic hydrocarbons, ne-aromatic hydrocarbon, ukumelana okuphezulu nokugqwala, kanye nempahla enhle ye-dielectric.
Isicelo
I-PVC Resin SG-3 Isicelo sokuthi:
1. Iphrofayela ye-PVC
Amaphrofayli ayinsimu yokusetshenziswa kwe-PVC ezweni lasekhaya, cishe i-25% yokusetshenziswa okuphelele kwe-PVC, ikakhulukazi ekwenzeni iminyango namafasitela nezinto zokonga amandla, futhi ukusetshenziswa kwabo kusekukhulu nokukhula.
2. Ipayipi le-PVC
Amapayipi e-PVC ayimboni yesibili enkulu esetshenziswayo, ukusetshenziswa kungamaphesenti angama-20 yenani eliphelele lokukhiqiza e-Domestic of China, i-PVC Pipe.
3. Ifilimu ye-PVC
Ifilimu ye-PVC efakiwe ingeyesithathu ukusetshenziswa kwenani elikhulu, cishe i-10% yawo wonke umthamo wokukhiqiza.
