Yintoni iPVC resin?
I-Poly Vinyl Chloride Resin okanye i-PVC Resin njengoko ibizwa ngokudumileyo, yiResin ye-thermoplastic enokuthi ithambe xa kushushubezwa.Igama eliqhelekileyo le polima yorhwebo yiVinyl.Ihlala ifumaneka ngohlobo lomgubo, iigranule zePVC zixhathisa kakhulu kwi-oxidation kunye nokuthotywa okubangelwa kukusabela kwe-atmospheric.
Yintoni ixabiso lika-K?
Ixabiso le-K lifutshane lokuqhuba kwe-thermal.I-Thermal conductivity, n: umlinganiselo wexesha lokuhamba kobushushu obuzinzileyo kwindawo yeyunithi yesixhobo esine-homogeneous eyenziwe yiyunithi yeqondo lobushushu kwicala elithe ngqo kulo mmandla weyunithi.
Ubala njani ixabiso lika-k?
Zingabalwa njenge-1 / (inani lokuchasana kweentlobo ezahlukeneyo ze-element (ixabiso layo le-R) + ukuchasana kwendawo yangaphakathi nangaphandle yento).
Ngaba kukho amabanga ahlukeneyo ePVC?
Kukho iintlobo ezimbini eziqhelekileyo zombhobho wePVC - ishedyuli ye-40 yePVC kunye neshedyuli ye-80 yePVC.Ishedyuli 40 yePVC idla ngokuba mhlophe ngombala kwaye ishedyuli 80 idla ngokuba yingwevu emnyama (zinokufumaneka kweminye imibala).Owona mahluko wabo ubalulekileyo, nangona kunjalo, kukuyilo lwabo.Umbhobho weShedyuli 80 uyilwe ngodonga olutyebileyo.
Isetyenziselwa ntoni iUPVC?
I-UPVC, ekwabizwa ngokuba yi-Unplasticized Polyvinyl Chloride, sisixhobo sokwakha esinesondlo esisezantsi esisetyenziswa endaweni yeplanga epeyintiweyo, ubukhulu becala kwiifreyimu zefestile kunye neesill xa kuhlonyelwa iglazing ephindwe kabini kwizakhiwo ezitsha, okanye ukubuyisela iifestile ezindala ezikhazimlisiweyo.

Yintoni i-chemical reaction ye-PVC?
I-PVC yenziwe ngokusebenzisa inkqubo ebizwa ngokuba yi-polymerization yokudibanisa.Le ndlela yokusabela ivula iibhondi eziphindwe kabini kwivinyl chloride monoma (VCM) ivumela iimolekyuli ezingabamelwane ukuba zihlangane zenze iimolekyuli ezinde.nC2H3Cl = (C2H3Cl)n vinyl chloride monomer = polyvinylchloride
Ziziphi iimpawu ezibonakalayo zePVC?
Iimpawu zomzimba kunye noomatshini: I-PVC yipolymer ye-atactic kwaye ngoko ke ngokuyimfuneko ayinamkristali.Nangona kunjalo, ngamanye amaxesha kwenzeka ukuba, ekuhlaleni, ngaphezu kwamacandelo amakhonkco amafutshane, i-PVC i-sydiotactic kwaye ingathatha isigaba se-crystalline, kodwa ipesenti ye-shear fracture ayinakudlula i-10 ukuya kwi-15%.Ubuninzi bePVC yi-1.38 g / cm3.
