He aha ngā pānga o ngā whakarerekētanga pānga ACR?

Ko te whakarerekē pānga ACR he copolymer kiriaku me te hanganga anga-matua, e whai wāhi nui ana ki te tukatuka kirihou pēnei i te PVC.
1. Te whakarei ake i te ātete pānga
Mā te whakaoho i ngā rārangi hiriwa me ngā here kutikuti mā roto i te elastomer paparanga matua, ka mimitihia te kaha pānga, ka whakapai ake i te kaha pānga o te hua (ina koa i roto i ngā taiao pāmahana iti); Ka taea e te hoahoa hanganga anga-matua te whakanui ake i te kaha pānga neke atu i te 6 ngā wā me te pupuri i te 90% pakari i te -40 ℃.
2. Te arotau i te mahi tukatuka
Whakatairanga i te kirihou PVC, whakapoto i te wā tukatuka, whakapai ake i te rere o te rewa me te pumau; Whakaitihia te āhuatanga o te whati rewa me te whakapai ake i te kounga o te extrusion o ngā kōtaha whakawhiti-wāhanga matatini
3. Whakapai ake i te mahi whānui
Whakapai ake i te maeneene o te mata o te hua, me te whakakore i ngā hapa pēnei i ngā kanohi ika me ngā tohu rere; Whakapai ake i te ātete ki te huarere, te ātete ki te wera, me te pumau matū, he mea tino pai mō ngā hua o waho.
4. Ngā painga tono motuhake
He tino hototahi ki te PVC, he ōrite te horapa hei karo i te kohikohinga; Ki te whakatauritea ki ngā whakarerekētanga pēnei i te CPE, he whānui ake te awhe pāmahana tukatuka a te ACR, ā, he nui ake te pai o te whakarerekētanga; Ka taea e te ACR mārama te pupuri i te whakawhiti mārama neke atu i te 85%, ā, he pai mō ngā hua mārama; Ko te nui o te tāpiri noa ko te 0.5-5phr, ā, me karo te whakaranu tika ki ngā whakakī kawakore. I tēnei wā, kua noho te Bangtai Petrochemical ACR hei tētahi o ngā whakarerekētanga pai mō ngā kōtaha PVC mārō, ngā paipa, me ngā koranu kirihou hangarau.
5. Kōwhiria te tauira ACR e tika ana
Kōtaha/Paipa: Ko ngā tauira taumaha ngota teitei te mea e pai ake ana, me te taumaha ngota neke atu i te 500000, ka taea te whakanui ake i te kaha rewa neke atu i te 40% me te pehi pai i te pakaru rewa o te whakaputanga; Ngā wāhanga werohanga/hua angiangi-pakipa: Ko ngā tauira taumaha ngota iti te mea e taunakitia ana, me te taumaha ngota o te 300000 ki te 500000 hei whakaiti i te matotoru rewa me te whakanui ake i te tere whakakī mā te 25% -30%; Me whakakotahi ngā hua mārama ki te MBS (tawhā wairewa 9.4-9.5) mō te whakamahinga matū, me te whakawhiti mārama o te >85%
