PVC resin mo paipa irrigation
PVC resin mo paipa vai,
mea mata paipa vai, pvc mo paipa fa'asusu,
PVC paipa irrigation:
(1) PVC irrigation paipa e sili atu ona tetee acid, alkali tetee ma corrosion tetee, lea e matua talafeagai mo alamanuia vailaau.O le puipui puipui o le PVC irrigation paipa e lamolemole.E laʻititi le malosi o le vai, ma o lona faʻamalosi e naʻo le 0.009, lea e maualalo ifo nai lo isi paipa.I lalo o le fua tutusa o le tafe, e mafai ona faʻaititia le lautele o paipa.O le malosi o le vai, o le malosi o fafo ma le aʻafiaga o paipa faʻafefe o le PVC e maualuga tele, lea e talafeagai mo le inisinia paipa i lalo o tulaga eseese.E taugofie ma fa'aoga lautele.
(2) PVC e mafai ona mulimuli lelei paipa irrigation le faagasologa o le tuputupu ae o fua o faatoaga e iloa ai irrigation faaonaponei.O le faʻaaogaina o le vai e mafai ona filifilia e tusa ai ma le susū faʻapitoa o mea totō ma eleele.
(3) PVC paipa irrigation e sili ona atoatoa e mafai ona faavae i luga o uiga o le kweather o loʻo i ai nei e ausia ai le saʻo saʻo o le vai ma le faʻamaʻaina i le aʻa o fualaau faʻatoʻaga metotia.O lenei mea e mafai ona fa'aitiitia ai galuega fa'atino.
(4) PVC e mafai ona felauaiga paipa vai e sili atu le talafeagai e tusa ai ma manaoga tuputupu aʻe o fualaʻau, lea e mafai ona faʻamautinoaina le faʻaleleia atili o le taimi ma le talafeagai o fualaʻau ma tuʻuina se faavae mautu mo le faʻaleleia o fua o fua.
(5) Irrigation paipa o loʻo faʻaaogaina lautele i le taulaga ma nuʻu i totonu ma fafo vai, faʻaleleia vai i tua, faʻatoʻaga faʻatoʻaga, paipa faʻafefeteina o le masima ma vailaʻau faʻainisinia, faʻafefe vai o pisinisi faʻatoʻaga, mine ventilation, sapalai vai ma alavai, sprinkler fanua. vai ma isi galuega tetele ma laiti.
O le Polyvinyl Chloride (PVC) o se resini thermoplastic laina e gaosia e le polymerization o le monomer vinyl chloride.Ona o le eseesega o mea mata, e lua auala o le synthesizing vinyl chloride monomer calcium carbide process ma le suauu.Sinopec PVC faʻaaogaina faiga faʻamalolo se lua, mai le Kamupani Iapani Shin-Etsu Chemical ma American Oxy Vinyls Company.O le oloa o lo'o i ai le lelei o le fa'a'a'ala'au fa'ama'i, mea fa'amama eletise lelei ma le mautu lelei o vaila'au.Faatasi ai ma le maualuga o le chlorine, o le meafaitino e lelei le afi ma mea e tineia ai le tagata lava ia.O le PVC e faigofie ona faʻaogaina e ala i le faʻafefe, tui tui, calendering, faʻafefeteina, faʻamalosi, faʻafefeteina ma le vevela, ma isi.
