E mōhio ana te hunga katoa e mahi ana i roto i te tukatuka PVC he pūnaha whakahinuhinu taurite te takirere haumaru mō te whai huatanga o te whakaputa me te kounga o te hua. Ahakoa kei te hanga koe i ngā paipa waikeri, i ngā kōtaha matapihi uPVC, i ngā taura hiko rānei, ka pā tika te tauira whakahinuhinu tika ki te tere o te raina, te mutunga o te mata me te ōritetanga o te puranga.

Heoi anō, kei te ara tonu mai tētahi pātai: nā te maha o ngā momo hinu whakahinuhinu e wātea ana, he aha te take e noho tonu ai te konupūmā stearate hei wāhanga matua e kore e taea te whakakapi i roto i ngā hanganga PVC? He aha te mea e wehewehe ai i tēnei mea mai i ētahi atu tāpiringa noa pēnei i te waikawa stearic me te ware pi PE?

I tua atu i te Whakahinuhinu: 3 Ngā Mahi Matua o te Konupūmā Stearate

He hinu whakahinuhinu pānga-rua te konupūmā stearate, e whakarōpūtia ana hei hinu whakahinuhinu ā-roto. Engari ko tōna uara i roto i ngā pūnaha PVC e kapi ana i te tukatuka, te pumau me te āhua:

Te Whakahaere i te Matotoru Rewa

Mā te whakaiti i te waku ā-roto i roto i te rewa PVC, ka tino whakapai ake i te matotoru o te rewa, ka whakapai ake hoki i te rere o ngā rauemi mā roto i ngā taputapu whakaputa. Ka pehi hoki i te wera nui o te kutikuti, ka whakaiti i te pirau ā-rohe me te werawera, ā, ka pupuri i te huringa tukatuka kia pumau.

Te Whakakore i te Waikawa (Te Whakapūmau i te Mahana-tahi)

He mahi nui tēnei kāore i roto i ngā hinu whakahinuhinu noa. Hei āwhina i te whakaū wera, ka hopukina e ia te hauwai pūhaumāota (HCl) i tukuna i te wā o te pirau wera o te PVC — ka ārai i te waikura o ngā taputapu me ngā pokepokea ai e ngā mea waikawa, me te whakaroa i te tapahi mekameka polymer me te whakapai ake i te mahi koroheketanga wera mō te wā roa.

Arotautanga Tukunga Pokepokea

He ngawari ngā āhuatanga whakahinuhinu o waho, ka pai ake te tukunga i waenga i te rauemi me te poka pokepokea ai, ā, ka whakaiti i te tūponotanga piri. Kāore i rite ki ngā whakahinuhinu o waho kaha ake, kāore e puta he puāwaitanga, he pupū rānei i te mata, ā, ka tiakina te kanapa me te kounga tirohanga o ngā wāhanga kua oti.

Wehenga Hangarau: Ngā Rerekētanga o ngā Hinu Whakahinuhinu e 3

Ko te pūnaha whakahinuhinu pakari e whakawhirinaki ana ki te mahi tahi o te whakahinuhinu ā-roto me te whakahinuhinu ā-waho. He mahi motuhake tā ia tāpiringa; mā te whakapoauau i a rātou ka arahi pea ki ngā rahunga whakaputa:

Konupūmā Stearate: He hinu whakahinuhinu matua o roto, he ngoikore te whakahinuhinu o waho

Ka mahi i roto i te rewa hei whakatairanga i te whakapūmautanga ōrite, me te whakarato hoki i te mimiti waikawa me te pumau tahi. Koinei te pou tuarā o te pūnaha whakahinuhinu, ā, kāore e taea te whakakapi ngāwari.

Waikawa Tūmā: He hinu whakahinuhinu noa iho

Ka mahi mā te heke ki te mata rewa hei whakaiti i te waku i waenga i te rauemi me ngā mata e pā ana ki te konganuku. Mā te whakamahi takitahi, mā te nui rawa rānei, ka roa ake te wā whakakī, ā, he maha ngā wā ka puta he hapa o te mata pērā i te puāwai me te waikura.

PE Wax: Hinu whakahinuhinu o waho tino pai

He mea motuhake mō te whakaiti i te piri o te konganuku, te whakanui ake i te kanapa o te mata, me te whakahohe i te tere o te raina. He pai ake i te waikawa stearic i ngā pāmahana teitei, engari kāore e whakarato i ngā painga mimiti waikawa, pumau wera rānei — e kore rawa e taea te whakakapi i te konupūmā stearate.

Te Mea Ngaro ki te Whakaputa Pūmau: Tauritehia tō Whakahinuhinu

Mō ngā kaihanga tukanga me te kounga, kāore he hinu whakahinuhinu whānui — he whakatakotoranga taurite anake.

Me mau tonu te ōwehenga tika o te whakahinuhinu ā-roto (e aro ana ki te konupūmā stearate) me te whakahinuhinu ā-waho (e ahu mai ana i te ware pi PE, i te waikawa stearic rānei). Mēnā kāore i te rawaka te konupūmā stearate, ngā hua rānei he iti iho te rahi o te matūriki, ka hua tika te kohikohinga o te paura, te horapa ngoikore o te masterbatch me ngā pikinga pēhanga rerekē i roto i te extruder, ka pā kino ki te whai huatanga me te hua.

E whakaū ana ngā raraunga whakaputa whānui he pai ake te horapa o te konupūmā stearate 325-mesh, he ōrite te matotoru, ā, he maeneene ake te mata, koia te mea pai rawa atu mō te hanga PVC kounga teitei, pumau.

Ka tukuna e mātou te konupūmā stearate kounga teitei me ngā whakatakotoranga matūriki tino tika me te mahi puranga ōrite, e wātea ana i roto i ngā tukunga ipu katoa (FCL) hei tautoko i ngā raina hanga PVC nui.

Tukuna mai he karere tika ki te tono i te Pepa Raraunga Hangarau (TDS) katoa, i ngā tauira whakamātautau rānei.
