Ukwelashwa Kwangaphandle kwe-Polytetrafluoroethylene (PTFE)

Njengomkhiqizi womthombo ochwepheshe wezindwangu ze-PTFE ezishisa kakhulu, i-Jiangsu Aokai New Materials izokwethula ukwelashwa okungaphezulu kwe-polytetrafluoroethylene (PTFE).

I-PTFE ifaka ukumelana nokushisa okuphezulu nokuphansi okuhle kakhulu, ukumelana nokugqwala kwamakhemikhali okuvelele, i-coefficient ephansi yokungqubuzana kanye nezakhiwo zokuzigcoba. Isetshenziswa kakhulu ku-electronics, imishini, okokusebenza kwamakhemikhali, i-aerospace, i-biomedicine neminye imikhakha, ithola isithunzi 'seNkosi Yepulasitiki' . Nokho, ngenxa yokungabi namandla kwamakhemikhali namandla aphansi angaphezulu, i-PTFE inzima ukuyihlanganisa nezinye izinto, ezikhawulela ukusetshenziswa kwayo ngokwezinga elithile. Ukuze uthuthukise ukunamathela phakathi kwe-PTFE nezinto ezihlukahlukene, izindlela zivame ukwamukelwa ukuthuthukisa umsebenzi ongaphezulu we-PTFE. Ngemikhiqizo ehlukene, i-Aokai New Materials ngokuvamile isebenzisa izindlela ezilandelayo zokuguqula indawo ye-PTFE.

1. Ukwelashwa Kwamakhemikhali Amanzi

Ukwelashwa ngamakhemikhali e-sodium-naphthalene  kungenye yezindlela ezisebenzayo zokuguqulwa kwendawo ye-PTFE. Ngenqubo elula nezindleko eziphansi, ukukhetha okuthandwayo ekukhiqizeni okungokoqobo embonini ye-PTFE ye-Aokai New Materials'.

Ukwelashwa kwe-sodium-naphthalene ikakhulukazi kusebenzisa isixazululo esibambayo ukuze kusabeleke ngamakhemikhali nge-PTFE, kususwa ama-athomu athile e-fluorine phezulu. Lokhu kushiya ungqimba lwe-carbonized futhi kwethula amaqembu amhlophe njengamaqembu e-hydroxyl, amaqembu e-carbonyl namabhondi angagcwele. Lawa maqembu asezindaweni ezishisayo andisa amandla angaphezulu we-polymer, anciphisa i-engeli yokuthintana futhi athuthukise ukumanzisa, ngaleyo ndlela aguqule i-PTFE isuke ekungaboshiwe ibe yisibopho.

2. Mechanochemical Bonding Indlela

Lapho ama-polymer engaphansi kwamandla angaphandle (isb., ukuchotshozwa, ukugaya, ukungqubuzana, njll.), amaketanga e-macromolecular ayaphuka futhi abhekane nokusabela kwamakhemikhali, okuhlanganisa i-mechanodegradation, i-mechanochemical crosslinking, i-mechanochemical grafting, i-block copolymerization kanye ne-polymerization ecushwe ukucindezeleka. Lokhu kwaziwa ngokuthi ukusabela kwe-polymer mechanochemical.

Ku-mechanochemical bonding, i-polymer ehlanganiswe ne-adhesive coated ihlikihlwa. Ngokusebenzisa isenzo se-mechanochemical, i-polymer surface idlula i-mechanodegradation ukuze yakhe ama-radicals mahhala ama-macromolecular, abese enza izibopho ezihlangene nama-molecule anamathelayo, enze isikhombimsebenzisi esiqinile sokubopha futhi athuthukise kakhulu amandla okubopha okuhlangene.

3. Indlela yokuncibilika kwezinga lokushisa eliphezulu

Isimiso esiyisisekelo sokushintsha izindawo ze-PTFE ngokuncibilika kwezinga lokushisa eliphezulu yilezi: emazingeni okushisa aphezulu, i-crystalline morphology yendawo ye-PTFE iyashintshwa, futhi amandla aphezulu, izinto eziboshelwe kalula ezifana ne-SiO₂ ne-Al powder ziyashumeka. Ngemva kokupholisa, kwakheka isendlalelo esilungisiwe esiqukethe izinto ezibophekayo endaweni ye-PTFE. Njengoba ama-molecule ezinto ezibophekayo angene kungqimba lwamangqamuzana ongaphezulu lwe-PTFE, ukwephula isibopho kudinga ukubhujiswa kwama-intermolecular, okuholela ekuqineni okukhulu kokubopha.

4. Indlela Yemisebe

I-PTFE ifakwe kuma-monomers asebenzayo e-polymerizable afana ne-styrene, i-fumaric acid, i-methacrylates namanye, bese ifakwe imisebe nge -Co-60 . Lokhu kubangela i-polymerization yamakhemikhali yama-monomers endaweni ye-PTFE, yakhe ungqimba lwe-polymer yokuxhunyelelwa okulula ukuyibopha. I-Grafting ibuye ibe lukhuni ebusweni, ikhulise indawo yokubopha futhi ikhulise amandla okubopha.

5. I-Plasma Treatment Technology

Ukwelashwa kwe-Plasma kungenye yobuchwepheshe obukhula ngokushesha kakhulu bokuguqulwa kwendawo ye-PTFE eminyakeni yamuva nje.

Umongo walobu buchwepheshe ukubeka isampula kudivayisi yokwelapha ye-plasma ezinikele, lapho ukuqhuma kwe-ion noma ukufakwa kwe-ion kunqamula amabhondi wamangqamuzana noma kwethula amaqembu asebenzayo endaweni ye-polymer, kusebenze indawo engaphezulu ukuze kuzuzwe ukuguqulwa. Ama-ion angaba amagesi angasebenzi, amagesi asebenza ngamakhemikhali noma izakhi zensimbi. Ukuqhunyiswa kwebhomu ngamagesi angenayo kungashintsha isakhiwo esingaphezulu se-polymer.

Ulwazi olungenhla lunikezwe i- Jiangsu Aokai New Materials Technology Co., Ltd.

Ukuze uthole imingcele enemininingwane, izimo zohlelo lokusebenza nezixazululo ezenziwe ngokwezifiso zohlu oluphelele lomkhiqizo wethu - okuhlanganisa indwangu ye-PTFE yokushisa ephezulu, i-PTFE itheyiphu yokushisa ephezulu, ibhande le-PTFE elinezinga eliphezulu lokushisa, amabhande angenamthungo emishini yokubopha, indwangu ye-PTFE enohlangothi olulodwa, indwangu engavimbeli izinga lokushisa eliphezulu ukuze ungathinteki ingilazi ye-fiber eyengeziwe thina:
