He aha ngā mate ka pā mai i te kounga iti o te polyethylene chlorinated CPE i roto i te tukatuka PVC?

Ko te polyethylene chlorinated (CPE) he hua whakarerekētanga chlorinated o te polyethylene kiato-teitei (HDPE), e whakamahia ana hei whakarerekētanga tukatuka mō te PVC. Ko te ihirangi chlorine o te CPE me noho i waenga i te 35-38%. Nā te mea he tino pai te ātete ki te huarere, te ātete ki te makariri, te ātete ki te mura, te ātete ki te hinu, te ātete ki te pānga (he elastomer te CPE), me te pumau matū.

Nā tōna ātete pai ki te huarere, te ātete makariri, te ātete mura, te ātete hinu, te ātete pānga (he elastomer te CPE), me te pumau matū, me tōna hototahi pai ki te PVC, kua riro te CPE hei whakarerekētanga whakapakeke pānga e whakamahia whānuitia ana i roto i te tukatuka PVC.
1 Te Whirihoranga Irahiko o te HDPE
Nā te rerekētanga o ngā āhuatanga tukanga i te wā o te tauhohenga polymerization o te PE, he rerekētanga ētahi o ngā hanganga ngota me ngā āhuatanga o tōna polymer HDPE. He rerekē anō hoki ngā āhuatanga o te CPE i muri i te whakakōroitanga o te HDPE me ngā āhuatanga rerekē. Me whiriwhiri e ngā kaihanga CPE ngā kapia paura motuhake HDPE e tika ana kia puta ai ngā kapia CPE whai tohu.
2. Ngā āhuatanga whakakōkō, arā, te tukanga whakakōkō
Ko te CPE, hei whakarerekētanga tukatuka PVC, ka hangaia mā te tauhohenga whakakōkō mā te whakamahi i te tikanga whakakōkō wai. Ko ngā āhuatanga matua o tēnei tukanga whakakōkō ko te pūngao mārama, te horopeta tīmatanga, te pēhanga tauhohenga, te pāmahana tauhohenga, te wā tauhohenga, me ngā āhuatanga tauhohenga whakakorekore. He tino māmā te kaupapa o te whakakōkō PE, engari he uaua ake te tikanga whakakōkō.
Nā te iti o te haumitanga ki ngā taputapu mō te hanga CPE, kua marara kē ngā whare hanga CPE iti puta noa i Haina. Ehara i te mea ka poke noa te taiao i te mea nei, engari ko tētahi o ngā take nui hoki o te kore pumau o te kounga o te CPE.
I tēnei wā, he nui ngā CPE kounga-iti kei te mākete. I te nuinga o te wā, e rua ngā momo CPE kounga-iti. Ko tētahi nā te korenga o ngā tikanga hangarau o ētahi whare whakaputa, me te korenga o ngā tukanga whakakōkōwaitanga tawhito. Ko tētahi atu tikanga ko te whakaranu i tētahi nui o te konupūmā kāponāte, te paura talc rānei ki roto i te CPE hei whakauru atu ki te whakataetae kore tika.
