Ngā Resin PVC Kounga SG3, SG5, SG7: Te Hangarau Whakarite mō ngā Otinga Ahumahi Mutunga-ki-Mutunga

Te Hoahoa Ngota me ngā Āhuatanga Ā-tinana

SG3 (Teitei - Teitei - Te Ngāwari o te Taumata)
I hangaia ki te tohu polymerization o te 1300 - 1500 me te uara K - o te 70 - 72, he roa ngā mekameka ngota ngota o tēnei momo e whakarei ake ana i te mauhere o te plasticizer. Ko tōna tohatoha matūriki 60 - 250μm e whakarite ana i te marara ōrite i roto i ngā hanganga matū ngohengohe, e āhei ai te 25 - 35g o te mimiti plasticizer mō ia 100g kapia. Ko te hanganga kore-āhua ka puta mai ka homai he roanga tino pai i te wā whati, he mea pai mō ngā hua e hiahia ana kia piko tonu me te kore e pakaru.

SG5 (Whānuitanga Waenga - Taumata)
Mā te whakataurite i te tohu polymerization o te 1000 - 1100 me te uara K - o te 65 - 67, ka tukuna e te SG5 he ara waenga hihiri. Ko tōna kiato matūriki kua whakapaitia (0.45 - 0.58g/mL) ka āwhina i te rere maeneene o te rewa i roto i te extrusion me te injection molding, ko te mimiti ngawari o te plasticizer (20 - 28g/100g) ka taea te whakawhiti mai i ngā uhi taura āhua-pakari ki ngā kōtaha ngāwari-iti. Mā te auau o te mekameka ngota ka whakaitihia ngā hapa tukatuka, ka whakarite kia rite te matotoru o te pakitara i roto i te extrusion paipa.

SG7 (Paenga Hangarau Pūmau)
Me te tohu whakapūhui o te 700 - 850 me te uara K - o te 60 - 62, ka whakatairangahia e te SG7 te whai huatanga o te tākai ngota hei whakapakari. Ko tōna hanganga matūriki kiato 40 - 180μm (kiato 0.50 - 0.62g/mL) ka whakaiti i ngā āputa i roto i ngā wāhanga i hangaia, ka whakarei ake i te ātete pānga i roto i ngā kōtaha whare. Ko te iti o te mimiti kirihou (15 - 22g/100g) ka taea te hanga i ngā hanganga tino pakari, ko te toenga vinyl monomer ≤3μg/g e tutuki ana i ngā paerewa haumaru whakapā-kai mō ngā tono tākai.

Pūnaha Āhuatanga Taupānga

SG3: Te Tohunga Ngāwari
I roto i ngā rāngai ahuwhenua, ka hangaia e ngā kiriata SG3 me ngā tāpiringa kirihou 40 - 50 phr he uhi whare kati kōtuhi kua whakapūmauhia e te UV, e whakataurite ana i te tuku mārama me te kaha ātete ki te haehae. Mō ngā tono hauora, nā te iti o te ihirangi monomer ka taea te whakamahi i ngā ngongo ngohengohe mō ngā mīhini dialysis, i roto i ngā hu, ka hangaia he kapu pīwariwari e mau tonu ana te āhua ahakoa ngā piki me ngā heke o te pāmahana.

SG5: Te Hōiho Mahi Ahumahi
Ka whakamahia e ngā kaihanga taura te whānuitanga kirihou 10 - 20 phr a SG5 hei hanga i ngā uhi whakamahana ātete-mura mō ngā whatunga hiko, e whakakotahi ana i te whakamahana hiko me te pakari ā-mīhini. I roto i te hanganga, ka puta ki roto i ngā rīpene hiri ātete-huarere mō ngā matapihi, ā, ko tōna pakeke ngawari ka ātete ki te pirau ozone. Ko ngā wāhanga motuka i hangaia ki te werohanga, pērā i ngā whakapaipai kuaha, ka whai hua mai i tōna ōwehenga pānga-kaha-ki-taumaha.

SG7: Te Toa Pūmau
Ka whakawhirinaki ngā pūnaha paipa ahumahi ki te kaha teitei o te SG7 mō ngā paipa waipara ātete matū me ngā puna wai kua whakatauria e te pēhanga. Ko ngā kōtaha matapihi kua puta, ina konatunatua ki te hauhā titanium, ka whakaatu i te pumau tae tino pai i roto i ngā taiao o waho. Ka whakamahia e ngā kaihanga hiko mō ngā whare taputapu i hangaia ki te werohanga, me te whakamahi i tōna pumau ā-ahu i te wā e huihui ana i te pāmahana teitei.

Aratohu Arotau Tukanga

Ngā Āhuatanga Whakahaere Wera
Me tino whakahaere te pāmahana o te SG3 (160 - 180°C) hei ārai i te pirau wawe; ahakoa te nui rawa o te 10°C ka taea te tuku waikawa hauwai, ka kōwhai ai. He rerekē, ka taea e te SG7 te tukatuka i te 180 - 200°C, ka tere ake te tere o te whakaputanga mō ngā paipa whānui, ahakoa ka nui ake i te 210°C ka pakaru te mekameka ngota.

Hoahoa Pūnaha Tāpiri
Whakapūmau: E hiahiatia ana e te SG3 he 1 - 2 phr o ngā whakapūmau hiato konupūmā-konutea hei ārai i te pirau wera i te wā tukatuka kirihou teitei, ko te SG7 ia e hiahia ana ki te 0.5 - 1 phr anake nā te iti o te ahotea i puta mai i te kirihou.
Whakahinuhinu: Ka whai hua ngā momo katoa i te 0.2 - 0.5 phr o te ware pi polyethylene, engari me nui ake pea te horopeta o te SG3 hei whakaiti i te waku o roto i ngā matū ngohengohe.
Ngā Tāpiri Mahi: Ka roa ake te ora o waho i ngā ārai mate i roto i ngā hanganga SG7, ā, ka whakarei ake ngā whakarerekētanga pānga i roto i te SG5 i te ātete ki ngā kohao mō ngā tono āhuarangi makariri.

Te Hiranga Hangarau i roto i te Hoahoa Resin

Mā te whakauru i te hangarau ngota ngota tika me te whakamātautau e whakahaerehia ana e te tono, ka whakamanahia e tā mātou putea SG3, SG5, SG7 ngā kaihanga ki te whiti i ngā herenga PVC tuku iho. Mai i te ngāwari e hiahiatia ana mō ngā taputapu hauora whakakorekore ki te hanganga hanganga e hiahiatia ana e te hanganga whare teitei, kei roto i ēnei kapia te whakakotahitanga o te pakari pūtaiao me te mahi ahumahi—te whakatakoto i ngā paearu hou mō ngā otinga polymer e whakahaerehia ana e te mahi.
