Me yasa PTFE Babban Zazzabi Harshen Harshen Wuta-Juriya a Buɗe Wuta? Menene Injin Ƙirƙirar Harshen Harshen Harshensa?

Jiangsu Aokai New Materials, babban mai kera masana'anta na PTFE masu zafin jiki, yayi bayani:

PTFE high-zazzabi masana'anta ne sosai harshen-resistant a bude wuta, yafi saboda da kwayoyin tsarin da thermal bazuwar inji ta core abu - polytetrafluoroethylene (PTFE). Jinkirin harshen sa baya dogara ga ƙarin abubuwan da ke hana wuta kamar kayan yau da kullun, amma ya samo asali ne daga sinadari na zahiri da kuma halayen ruɓewa na musamman.

Ana iya fahimtar wannan daga matakai uku:

1. Ƙarfin Kwayoyin Halitta 'Makamai': Ƙarfin Ƙarfafa Ƙarfafawa da Ƙarfafa Kariya

Ƙarfin  carbon-fluorine (C–F) haɗin gwiwa : PTFE kwayoyin halitta sun ƙunshi kashin bayan sarkar carbon da ke kewaye da atom ɗin fluorine. Haɗin CF-F ɗaya ne daga cikin sanannun haɗin sinadarai masu ƙarfi, tare da ƙarfin haɗin kai kusan 485 kJ/mol. Ana buƙatar makamashi mai ƙarfi (zazzabi) don karya shi, samar da layin farko na tsaro.

Tasirin  garkuwar atom ɗin fluorine : Manyan zarra na fluorine da ba su da caji suna cike da yawa, suna aiki azaman sulke mai kauri wanda ke rufe sarkar carbon na ciki. Wannan shingen yana hana yawancin sinadarai (ciki har da iskar oxygen) isa ga sarkar carbon kuma yana da karfi da hana halayen iskar oxygen da ake bukata don konewa.

2. Rashin Konewa Bazuwar: Depolymerization maimakon ƙonewa

·  Sarkar juzu'i kafin hadawan abu da iskar shaka : A karkashin yanayin zafi mai zafi, ƙarancin ƙarancin carbon-carbon (C–C) haɗin gwiwa tsakanin PTFE karya kafin haɗin C-F. Sarƙoƙin ƙwayoyin cuta sun fara raguwa kafin iskar oxygen ta shiga cikin halayen.

Babban  samfuri shine monomer : Bayan karya, PTFE galibi yana jurewa depolymerization , yana sakin tetrafluoroethylene (C₂F₄) monomers daga ƙarshen sarkar. Kayan yana vaporizes maimakon fuskantar tashin hankali konewa wanda ke sakin dumbin zafi da iskar gas mai ƙonewa.

·  Tasirin shinge na gas-lokaci : C₂F₄ iskar gas daga depolymerization ya fi iska kuma ya zauna kusa da saman, yana samar da wani yanki na gaseous na wucin gadi wanda ke diluting iskar oxygen kuma yana kara hana konewa.

3. Taimakawa Matsayin Gilashin Fiber Substrate

PTFE high-zazzabi masana'anta ne wani hadadden sanya ta shafi PTFE uwa gilashin fiber zane. Gilashin fiber kanta abu ne wanda ba zai iya ƙonewa ba. A matsayin kwarangwal na tsari, yana tabbatar da cewa ko da saman PTFE Layer ya cika cinyewa a ƙarƙashin matsanancin zafi, kayan ba ya narke ko drip kamar filastik mai tsabta, yana kiyaye mutuncin tsarin da kuma hana yaduwar harshen wuta.

Ya kamata a jaddada cewa PTFE ba ta da wuta , ba gaba ɗaya ba mai ƙonewa. Lokacin da zafi sama da wurin narkewa (327 ° C) kuma ya ci gaba, yana lalata kuma yana fitar da hayaki mai guba. Yawanci yana jure yanayin zafi na dogon lokaci har zuwa 260 ° C kuma yana tsayawa a taƙaice a 300-360 ° C.

Rushewa a cikin buɗe wuta : Lokacin da aka fallasa kai tsaye ga buɗe wuta (nisa sama da zafin jiki na ruɗuwa), Layer na PTFE yana rubewa, amma tsarin baya haifar da isasshen zafi ko abubuwan konewa don ci gaba da konewa. Haɗe tare da tallafin fiber gilashin, harshen wuta ba zai iya yadawa ba.

A taƙaice, PTFE high-zazzabi masana'anta ne harshen wuta-resistant saboda ta core abu PTFE an molecularly tsara don tsayayya konewa .High-makamashi sunadarai shaidu, musamman bazuwar hanyoyi, da mara-flammable gilashin fiber kwarangwal tare samar da wani karfi fireproof shãmaki.

ne ya samar da bayanan da ke sama Jiangsu Aokai New Materials Technology Co., Ltd .

Don cikakkun sigogi, yanayin aikace-aikacen da keɓaɓɓen mafita na kewayon samfuran mu - gami da masana'anta mai zafin jiki na PTFE, tef mai zafin jiki mai zafin jiki, PTFE high-zazzabi raga bel, bel maras kyau don injunan haɗin gwiwa, zane mai gefe guda PTFE, babban zafin jiki mai juriya mai ɗaukar bel, babban zafin jiki mai alaƙa da samfuran fiber da sauran samfuran fiber don Allah
