Whakataki hua

1,Ngongo PtfeKo te polytetrafluoroethylene tētahi atu ingoa mō te polytetrafluoroethylene, ko te whakarāpopototanga Ingarihi ko PTFE, (e mōhiotia whānuitia ana ko "Plastic King, Hara"), ā, ko te tātai matū ko -(CF2-CF2)n-. I kitea tūponotia te Polytetrafluoroethylene i te tau 1938 e te kaimātai matū a Tākuta Roy J. Plunkett i DuPont.'I te Taiwhanga Jackson i New Jersey, USA i tana ngana ki te hanga i tētahi chlorofluorocarbon hou mō te hauhautanga matū. Ko ngā hua o tēnei rauemi e kiia whānuitia ana ko te "paninga kore-piri"; he rauemi polymer hangai e whakamahi ana i te fluorine hei whakakapi i ngā ngota hauwai katoa i roto i te polyethylene. He ātete tēnei rauemi ki ngā waikawa, ki ngā kawakore, me ngā momo whakarewa waro, ā, tata kore e rewa i roto i ngā whakarewa katoa. I taua wā anō, he āhuatanga ātete pāmahana teitei te PTFE, ā, he tino iti te tauwehenga waku, nō reira ka taea te whakamahi hei huarahi whakahinuhinu, ā, kua waiho hoki hei paninga pai mō te paparanga o roto o ngā kohua kore-piri me ngā paipa wai.

Ko ngā rauemi o tēnei hua e whakamahia ana mō ngā hua e whai ake nei:

PTFE, FEP, PFA, ETFE, AF, NXT, FFR.

PTFE: Ka taea te whakamahi tonu i te paninga kore-piri PTFE (polytetrafluoroethylene) i te 260°C, me te pāmahana whakamahinga mōrahi o te 290-300°C, he tino iti te tauwehenga waku, he pai te ātete ki te kakahu me te pumau matū tino pai.

FEP: Ka rewa, ka rere te paninga kore-piri o te FEP (fluorinated ethylene propylene copolymer) hei hanga i tētahi kiriata kore-pūpū i te wā e tunua ana. He tino pai te pumau matū me ngā āhuatanga kore-piri. Ko te pāmahana whakamahinga mōrahi ko te 200℃.

PFA: Ka rewa, ka rere te paninga kore-piri o te PFA (perfluoroalkyl compound) i te wā e tunua ana hei hanga i tētahi kiriata kore-pūwero pērā i te FEP. Ko te painga o te PFA he teitei ake te pāmahana whakamahi tonu o te 260°C, he pakari ake, he pakari hoki, ā, he tino pai mō te whakamahi i roto i ngā tono ārai-piri me te ātete matū i raro i ngā āhuatanga pāmahana tiketike.

Ko te PTFE (Polytetrafluoroethene) he rauemi pūmua hangai e whakamahi ana i te fluorine hei whakakapi i ngā ngota hauwai katoa i roto i te polyethylene. He ātete tēnei rauemi ki ngā waikawa, ki ngā kawakore, me ngā momo whakarewa waro, ā, kāore e rewa i roto i ngā whakarewa katoa. I taua wā anō, he āhuatanga o te ngongo ptfe ko te ātete ki te pāmahana teitei, ā, he tino iti te tauwehenga waku, nō reira ka taea te whakamahi mō te whakahinuhinu, ā, kua waiho hoki hei paninga pai mō ngā woka me ngā paipa wai ngāwari ki te horoi. Ka taea te whakamahi mō te ātete ki te waikura o ngā paipa, te ātete ki te pāmahana teitei me te iti, me te ātete ki te waikura. Ka whakamahia i roto i ngā taiao uaua pēnei i te whakahinuhinu, te hangarau, te hikohiko, ngā taputapu hiko, me te rererangi.

Ngā āhuatanga o te hua

1, Ātete pāmahana teitei me te iti: he iti noa te pānga ki te pāmahana, he whānui te awhe pāmahana, he pāmahana e tika ana -65 ~ 260 ℃.

2, Kāore e piri: Kāore te nuinga o ngā matū e piri ki te kiriata PTFE. He pai hoki te mahi kore-whakararuraru a ngā kiriata tino angiangi. 2. Ātete wera: He tino pai te ātete wera o te kiriata paninga PTFE, ā, he iti hoki te pāmahana. Ka taea e ia te tu atu i ngā pāmahana teitei tae atu ki te 300°C i roto i te wā poto, ā, ka taea te whakamahi tonu i waenga i te 240°C me te 260°C. He tino pumau te pāmahana. Ka taea te mahi i ngā pāmahana tio me te kore e pakarukaru, ā, kāore e rewa i ngā pāmahana teitei.

3、Āhuatanga reti: He nui ake te tauwehenga waku o te kiriata paninga PTFE. Ka rerekē te tauwehenga waku ina reti te kawenga, engari ko te uara kei waenganui i te 0.05-0.15 anake.

4, Ātete makuku: Kāore te mata o te kiriata paninga PTFE e piri ki te wai me te hinu, ā, e kore e ngāwari te piri ki te otinga i te wā e mahi ana. Mena he iti noa te paru, horoia noa. He poto te wā e moumouhia ana, ka penapena i ngā hāora mahi, ka whakapai ake hoki i te pai o te mahi.

5, Ātete kakahu: He tino pai te ātete kakahu i raro i te kawenga nui. I raro i tētahi kawenga, e rua ngā painga o te ātete kakahu me te kore pokanoa.

6, Ātete ki te waikura: Kāore te PTFE e waikura i ngā matū, ā, ka taea te tu atu ki ngā waikawa kaha katoa (tae atu ki te aqua regia) me ngā waikura kaha engari ko ngā konganuku kawakore rewa, ngā mea kua whakapūhaumāotahia me te hauwai konutai i runga ake i te 300°C. Ko te mahi a te kaiwhakaiti me ngā whakarewa rauropi maha ka taea te tiaki i ngā wāhanga mai i tetahi momo waikura matū.

āhuatanga matū

1, Āraitanga: Kāore e pāngia e te taiao me te auau, ka taea e te ātete rōrahi te tae ki te 1018 ohm·cm, he iti te mate uruhanga, ā, he teitei te ngaohiko pakaru.

2, ātete pāmahana teitei me te iti: he iti noa te pānga ki te pāmahana, he whānui te awhe pāmahana, he pāmahana e tika ana -190 ~ 260 ℃.

3, Whai-whakahinuhinu: Ko te iti rawa o te tauwehenga o te waku i roto i ngā kirihou, ā, he rauemi whakahinuhinu kore-hinu pai rawa atu.

4, Kore-piripiri te mata: e mōhiotia ana kāore e taea e ngā rauemi totoka te piri ki te mata, he rauemi totoka tēnei me te iti rawa o te kaha o te mata.

5, ātete ki te huarere, te ātete ki te irahiko me te iti o te uruhanga: ahakoa te roa o te wā e pāngia ana e te hau, ka noho tonu te mata me te mahi.
