Chifukwa chiyani chubu cha PTFE ndi chubu chosankhidwa ndi opanga zida zamankhwala ambiri？

Opanga zida zamankhwala nthawi zonse akuyang'ana kwambiri kukonza mapangidwe a zida zawo kuti awonjezere magwiridwe antchito awo. Pali njira zosiyanasiyana zomwe opanga ayenera kuganizira akamagulitsa chinthu. Chimodzi mwa zinthu zomwe zimafala kwambiri mumakampani opanga zida zamankhwala ndi kulumikiza zitsulo ndi pulasitiki. Chinanso ndikulola kuti deta ya "nthawi yeniyeni" ifike pamakina odziwira matenda. Opanga zida zamankhwala nthawi zonse amakhala akuyenda kuti apeze zinthu zabwino kwambiri kuti akwaniritse zomwe zikuchitika posachedwa komanso zosowa zaumoyo.

Kuphatikiza apo, opanga zida zamankhwala amatsatira malamulo okhwima omwe akhazikitsidwa ndi FDA. Zipangizo zachipatala zimagawidwa m'magulu atatu, I-III. Zipangizo zachipatala za Gulu lachitatu ndizo zolamulidwa kwambiri. Kuphatikiza pa malamulo ambiri, opanga zida zachipatala ayenera kuda nkhawa ndi momwe zida zawo zimagwirira ntchito chifukwa zimatha kuwononga. Chipangizo chachipatala cholakwika chingaphe munthu. Tsoka ilo, wopanga zida zachipatala akhoza kuimbidwa mlandu ngati chipangizocho chasiya kugwira ntchito ndikuyambitsa vuto. Ubwino wa chinthucho ndi wofunikira kwa opanga zida zachipatala.

Popeza pali zovuta izi, opanga zida zamankhwala ayenera kugwiritsa ntchito zida zabwino kwambiri, ndichifukwa chake nthawi zambiri amagwiritsa ntchitoChidebe cha PTFEemonga chisankho chawo cha bafaePTFE ndi fluoropolymer yomwe yakhalapo kwa nthawi yayitali. Ngati mudamvapo za ptfe tube, izi ndi zomwe tikulankhula tikatchula za PTFE. Fluoropolymer ndi mankhwala omwe ali ndi ma fluorocarbon ambiri.

Pali makhalidwe angapo omwe amapangitsaChidebe cha PTFEeImawonekera bwino kwambiri. Choyamba, monga momwe zilili ndi ma fluoropolymers onse, PTFE ili ndi makhalidwe osamatirira. Ichi ndichifukwa chake nthawi zambiri imagwiritsidwa ntchito popanga mbale zophikira. PTFE siigwiranso ntchito ndi mankhwala ambiri, kotero opanga sayenera kuda nkhawa ndi zotsatirapo zoyipa. PTFE ili ndi coefficient yotsika kwambiri ya kukangana kuposa polima iliyonse. Ili ndi kutentha kwakukulu kwa madigiri 500 Fahrenheit, ndipo ili ndi mphamvu zamagetsi zabwino kwambiri. Imakhalanso yolimba kwambiri ku kuwala kwa UV komanso kupirira nyengo.

Opanga zipangizo zachipatala amagwiritsa ntchito mapaipi a PTFE pazinthu zosiyanasiyana. Ndi fluoropolymer yomwe imasankhidwa kwambiri kwa opanga mawaya amagetsi, opanga magalimoto, ndi zina zambiri. Mapaipi a PTFE ndi amodzi mwa mitundu yambiri ya mapaipi a fluoropolymer.eyoperekedwa pano ku Fluorotherm. Tikukulimbikitsani kwambiri kuti muyang'ane zopereka zathu zonse kuti mudziwe bwino lomwe fluoropolymer yomwe imagwira ntchito bwino kwambiri pamakampani anu komanso momwe imagwiritsidwira ntchito.
