o le a le PVC malo?
o le a le PVC malosi?,
fa'aoso PVC malo, uPVC,
PVC malosi (fa'aigoa ouPVC) o le polymer lona tolu e sili ona lautele gaosia.I tulaga o extrusions palasitika, PVC o le sili ona extruded maaa palasitika.E taugofie, e iai mea e mafai ona toe fa'aaogaina ma e tele mo le fa'aoga i totonu ma fafo.E faia e lenei meafa'aoso PVC malosa filifiliga lauiloa mo le tele o ituaiga o talosaga.O le uPVC e fa'atusa mo le PVC e le'i fa'apipi'iina ma o mea e fa'aalia i lona umi ma le malosi.Ose palasitika sili ona fetuutuunai, lelei mo le tele o talosaga
Malosi o le PVC meatotino
O le PVC o se polymer malosi e mafai ona faʻaleleia atili i le faʻaaogaina o suiga o aʻafiaga.O mea fa'apipi'i PVC malosi e iai le malosi fa'aola kemikolo.O lona uiga o paipa PVC malo e mafai ona faigofie ona uelo, faʻapipiʻi ma faʻapipiʻi ia te ia lava - lelei mo soʻoga i paipa.O lona tete'e atu i le pala e fa'aosoina ai fa'amatalaga ma'a'a PVC, vaega ma 'oti talafeagai mo si'osi'omaga i fafo.O le PVC e iai fo'i mea fa'amama lelei mo fa'aoga eletise eletise maualalo.Fa'afetai i ona fa'amanuiaga e tele,fa'aoso PVC malos ma le malu PVC paipa ua faʻaaogaina ma le manuia i totonu ma fafo.
Fa'aoga PVC extrusions malo
O le PVC malosi e faʻaaogaina lautele i le fausiaina o paipa vai ma otaota, conservatories, gutters, faʻapipiʻiina, puipui ma puipui puipui ma faʻamalama faʻamalama ona o ona mea sili ona lelei vevela ma mautu.I felauaiga talosaga o le uPVC e faʻaaogaina fafo mo tino taʻavale, karavan ma vaʻa, ma totonu mo le faʻatupuina o mea faʻalelei, talu ai e maua i le tele o lanu ma faʻamaeʻaina.I le vaega fa'atau oloa fa'aaliga fa'atau, fata e teu ai, fasi pepa pepa ma fa'amau pepa lautele e gaosia uma mai le PVC malo.
Fa'aalia le palasitika thermo, e le mafai ona solu i totonu o le vai, penisini ma le ava malosi, fula pe solo i le eter, ketone, chlorinated aliphatic hydrocarbons, ma mea manogi hydrocarbon, maualuga tetee i le pala, ma meatotino dielectric lelei.
Fa'atatauga
PVC Resin SG-3 Talosaga i:
1. PVC talaaga otooto
Talaʻaga o le fanua o le taumafa PVC i totonu o le atunuʻu, e tusa ma le 25% o le aofaʻi o le PVC, aemaise lava mo le faia o faitotoʻa ma faʻamalama ma mea e faʻaolaina ai le malosi, ma o loʻo tele pea ma tuputupu aʻe la latou talosaga.
2. PVC paipa
O paipa PVC o le 2nd pito sili ona tele faʻatau pisinisi, O le faʻaaogaina o le 20% o le aofaʻi o le gaosiga gafatia i totonu o le atunuʻu o Saina, le PVC Pipe.
3. PVC ata tifaga
O le ata PVC na faʻauluina o le lona tolu o le aofaʻi tele o taumafa, e tusa ma le 10% o le aofaʻi o gaosiga gafatia.
