Mea mata mo le gaosia o paipa PVC
Mea mata mo le gaosia o paipa PVC,
PVC resini, PVC e gaosia ai paipa,
S-1000 polyvinyl chloride resin o lo'o gaosia e ala ile fa'agasologa ole polymerization fa'amalolo e fa'aaoga ai le vinyl chloride monomer e fai ma mea mata.O se ituaiga polymer faʻapipiʻi faʻatasi ma se faʻatusatusaga o le 1.35 ~ 1.40.O lona tulaga faʻafefe e tusa ma le 70 ~ 85 ℃.Le lelei le mautu vevela ma le malamalama tetee, sili atu i le 100 ℃ po o se taimi umi i lalo o le la hydrogen chloride e amata ona pala, gaosiga palasitika e manaʻomia le faʻaopoopoina o mea faʻamautu.O le oloa e tatau ona teuina i totonu o se faleteuoloa mago ma faʻafefe.E tusa ai ma le aofaʻi o le plasticizer, e mafai ona fetuunai le palasitika vaivai, ma e mafai ona maua le resini paʻu e ala i le polymerization emulsion.
Vasega S-1000 e mafai ona faʻaaogaina e gaosia ai ata malūlū, laupepa, paʻu tagata, paipa, paʻu faʻapipiʻi, lalo, paipa puipuia o le uaea, afifiina ata, solo ma isi mea vaivai.

O paipa PVC o loʻo gaosia e ala i le extrusion o mea mata PVC, ma e masani ona mulimuli i laʻasaga tutusa o faʻagaioiga masani o paipa:
1. Fafagaina o mea mata e taʻua o le resini ma le faʻatumu i totonu o le PVC twin screw extruder;
2. liusuavai ma faʻamafanafana i le tele o sone extruder;
3. Tu'u i totonu o se mate e fau ai se paipa;
4. Fa'amalieina o le paipa fa'apena (e ala i le sasaina o le vai i luga o le paipa);ma
5. Otiotiina o paipa PVC i le umi e manaʻomia.
O mea mata'ina mo le gaosia o paipa PVC o resini ma fa'atumu (tele calcium carbonate, po'o e masani ona ta'ua o ma'a).Ole fa'afefiloi masani ole 1 kilokalama (kg) o resini ma le 1 kilokalama ole fa'atumu.O faʻagasologa o gaosiga e tele lava ina faʻaogaina, faʻatasi ai ma tagata faigaluega e fafagaina mea mataʻutia i le amataga o le faagasologa, mataʻituina le vevela i le faagasologa ma siaki le oloa mulimuli mo soʻo se faʻaletonu manino aʻo leʻi faʻapipiʻiina ma lafoina i tagata faʻatau.O tagata faigaluega uma ua a'oa'oina ma e mafai ona latou fa'atinoina uma nei galuega ma le fa'aamana'ia.O mea autu mo le gaosiga o paipa PVC o se mea paʻu e taʻua o le PVC resin.
