I-Jiangsu Aokai New Materials, umkhiqizi ochwepheshile we-PTFE kanye nemikhiqizo ye-fluoroplastic, wabelana ngemibandela yokukhetha ye-PTFE yetheyiphu yokushisa ephezulu yokubhidliza kanye nezimo ezimelene nezinti emishinini yokubumba umjovo.
I. Ukukhethwa Okusekelwe Emazingeni Okushisa: Gxila Ekumelana Nokushisa Kwesendlalelo Esinamathelayo ne-Substrate
Itheyiphu ye-PTFE iqukethe izingxenye ezimbili: i-substrate (ngokuvamile indwangu ye-fiberglass ehlanganiswe ne-PTFE) kanye ne-adhesive esekelayo. Isendlalelo sokunamathela ngokuvamile siyibhodlela lokusebenza.
1. Izinga lokushisa eliqhubekayo lokusebenza ≤ 260°C (Amapulasitiki avamile namapulasitiki obunjiniyela ayingxenye)
Izinto ezisetshenziswayo: I-PE, PP, PS, ABS, i-PVC ethambile, i-EVA, kanye ne-PA, i-PBT nezinye izinto ezicutshungulwa emazingeni okushisa aphansi. Ukukhetha okunconyiwe: Itheyiphu ye-PTFE evamile eqiniswe nge-fiberglass ene-silicone ezwela ukucindezela (PSA). Ugqinsi oluphakanyisiwe: 0.13 mm noma 0.18 mm, ukuvumelana kokulinganisa nokuqina kwesevisi. Amanothi abalulekile: Lolu wuhlu olulungile lokusebenza lwetheyiphu ye-PTFE, equkethe ukuqina okuhle kakhulu kwamakhemikhali nokusebenza kokukhululwa.
2. Izinga lokushisa eliqhubekayo lokusebenza 260°C ~ 300°C (Amapulasitiki obunjiniyela asezingeni eliphezulu)
Izinto ezisetshenziswayo: I-PC, i-PA66, i-POM, i-PET, i-PPA yokushisa ephezulu, i-PPO eguquliwe kanye nezinye isikhunta somjovo ophezulu wokushisa. Ukukhetha okunconyiwe: Itheyiphu ye-Fiberglass PTFE ehlanganiswe nokunamathelisa abicah angavimbeli izinga lokushisa eliphezulu. Ingcina ye-silicone evamile izoguga ngokushesha, ilahlekelwe amandla futhi ishiye izinsalela ngaphansi kwalolu banga lokushisa. Ugqinsi oluphakanyisiwe: 0.18 mm noma 0.25 mm. Izendlalelo ezinamathelayo eziwugqinsi kanye ne-substrate ziletha ukubhafa okungcono kokushisa nokumelana nokuguga. Ukuqinisekisa okubalulekile: Cacisa amasistimu okunamathelayo anokumelana nezinga lokushisa elingaphezu kuka-280°C kubahlinzeki, futhi uqinisekise ukuthi okunamathelayo kuzongcolisa isikhunta ngaphansi kokushisa okuphezulu.
3. Izinga lokushisa eliphakeme elisheshayo elingu-300°C ~ 400°C (Amapulasitiki akhethekile asezingeni eliphezulu noma izindawo ezishisayo zendawo)
Izinto ezisetshenziswayo: I-PEEK, i-LCP, i-PPS, i-PEI, ikakhulukazi etholakala eduze kwamabhomu omgijimi ashisayo namakhanda e-fae extrusion. Isexwayiso sokukhetha: Akukho okunamathelayo okuthembekile okuzwela ukucindezela okungamelana naleli banga lokushisa. Noma iyiphi itheyiphu ye-PTFE enamathelayo izohluleka khona manjalo, ifake i-carbonize futhi ingcolise imikhiqizo eqediwe. Ezinye izixazululo:
1. Indwangu ye-fiberglass ye-PTFE enganamatheli, emiswe ngomshini ngokusebenzisa amafreyimu abamba isikhunta, amapheshana noma okunamathelayo okunezinga lokushisa eliphezulu (okunamathelayo okungazweli ingcindezi njengama-silicone sealant).
2. Itheyiphu yefilimu ye-PFA ene-fluorinated ngokugcwele, enamathiselwe endaweni yokubunjwa nge-welding yomoya oshisayo. Imelana no-260°C okuqhubekayo kanye nokuchayeka kwesikhashana okungu-300°C, nokho ayikwazi ukushintshwa ngendlela eguquguqukayo njengetheyiphu yokuzinamathisela. Esinye isiphakamiso esithuthukisiwe: Ezimweni ezinjalo zezinga lokushisa eliphezulu, isikhunta se-PTFE enamathelayo noma i-nano Ceramic ukumelana nezinga lokushisa eliphezulu inconywa kakhulu.
II. Ukukhetha Okususelwe Kwempahla Ebalulekile: Ukumelana Nokufana Kwe-Wear, Ukumelana Nokugqwala kanye Nezidingo Zokukhishwa
Izakhiwo zomzimba nezamakhemikhali zepulasitiki encibilikisiwe zinquma ukusebenza kwendawo edingekayo namandla esakhiwo setheyiphu.
1. Izinto ezithambile / ezijwayele ukubunjwa
Izinto ezimele: i-EVA, ingcina yokuncibilika eshisayo, i-TPE, i-TPU, amamaki athile e-PP ashintshiwe. Amaphuzu abalulekile okukhetha: Khetha itheyiphu ekhishwa kakhulu enokuqukethwe okuphezulu kwe-PTFE nokunamathela okuminyene. Beka kuqala itheyiphu yefilimu ye-PTFE emsulwa (ngaphandle kokuqiniswa kwe-fiberglass, amandla aqinile aqinile, afanele izindawo ezinokucindezeleka okuncane) noma itheyipu ye-PTFE ye-fiberglass efakwe ngokugcwele. Indawo eseduze ne-PTFE ehlanzekile iletha ukusebenza okuphakeme kokulwa nezinti.
2. I-Glass fiber / mineral egcwele izinto eziqinisiwe
Izinto ezimele: I-Glass fiber reinforced PA, PP, PBT, i-calcium carbonate egcwele i-PP. Indlela yokugqoka: Ukuncibilika okugelezayo kusebenza njengephepha lesandpaper eliwuketshezi, okuhuqa ngokushesha okujwayelekile kwe-PTFE; i-fiberglass substrate eveziwe izodala ukukhubazeka kokunamathela. Amaphoyinti angukhiye wokukhetha:
1. Ukubaluleka kokuqina: Khetha itheyiphu engagugi esindayo engu-0.25 mm noma ugqinsi.
2. Ukuqiniswa kwesakhiwo: Khetha imikhiqizo enezingqimba eziningi ze-PTFE noma ukwelashwa kokuqina kwendawo esikhundleni sokunamathela okukodwa okuncane.
3. Isu lokushintsha: Phatha itheyiphu njengento evamile esetshenziswa kulezo zimo zokusebenza, futhi usethe imijikelezo yokuhlola kanye nokushintshanisa ngezikhathi ezithile esikhundleni sokuphishekela impilo yesevisi yaphakade.
3. Izinto ezinezithasiselo ezonakalisayo noma ezimanzi
Izinto ezimele: I-PVC eqinile (ikhulula i-HCl), inhlanganisela ye-flame retardant (i-brominated, imvula esekelwe ku-phosphorus-based flame retardant), izinsiza zokucubungula ezine-fluorinated. Imodi yokwehluleka: Imvula iguguleka isendlalelo sokunamathisela noma ingene ku-substrate, okuholela ekuqhumeni kwe-tape kanye ne-delamination.
1. Ukumelana namakhemikhali okunamathelayo: Qinisekisa ukuthi i-silicone enamathelayo inokungena okwanele ngokumelene nama-asidi abuthakathaka, ama-plasticizers nezinye izimvula.
2. I-substrate eminyene: Khetha itheyipu ene-fiberglass elukwe ngokuqinile futhi evalwe ngokugcwele ye-PTFE ukuvimbela ukungena kwegesi/uketshezi olulimaza ingcina esekelayo.
3. Ukuthuthukiswa kokukhipha umoya: Hlanganisa ukukhishwa kwesikhunta se-vacuum noma imigudu eyengeziwe yokukhipha umoya uma kunesidingo ukuze unciphise ukunqwabelana kwemvula endaweni okusebenzela kuyo itheyiphu kusukela emthonjeni.
4. Izinto ezithinta i-static
Izimo ezijwayelekile: Ukubumba komjovo wengxenye ye-elekthronikhi, i-high-flow PP ifilimu extrusion. Ukukhetha okunconyiwe: Itheyiphu ye-PTFE engaguquguquki (itheyiphu ye-PTFE emnyama embozwe ngekhabhoni eqhubayo emnyama noma isendlalelo esikhethekile esilwa ne-static) ukuze kugwenywe ukukhangiswa kothuli nobungozi bokukhishwa kwe-electrostatic.
III. Ukuzivumelanisa nezimo Ngokusekelwe Kwezisetshenziswa Nezimo Zokusebenza
1. Ukubunjwa kwesikhunta sokujova
Imigodi, izilayidi kanye neziphakamisi: Itheyiphu ivamise ukusetshenziswa ezindaweni ezinamathela isikhunta. Itheyiphu ezacile engu-0.13 mm enokwandiswa okuhle iyadingeka ukuze ilingane izindawo ezigobile eziyinkimbinkimbi. Gwema izikhonkwane ze-ejector nezikhala zokungena; qaphela izingxenye ezinembayo njengoba ukujiya kwetheyiphu kuzoshintsha ukubekezelela kobukhulu bomkhiqizo. Amapuleti omgijimi oshisayo namathiphu we-nozzle: Amazinga okushisa aphezulu kakhulu asebenza lapha; Indwangu ye-PTFE enganamathelisi engaguquki kuphela engasetshenziswa ukuvimbela ukunamathela kwe-flash. I-tape yokuzinamathisela ayivunyelwe ngokuphelele.
2. Extruder kanye nemishini engezansi
Izindebe / izitolo zokukhipha i-Extrusion: Vimbela ukunqwabelana kokuncibilika kanye nezintambo endaweni yokukhipha amanzi. Khetha itheyiphu yokukhishwa okuphezulu (0.08 mm–0.13 mm) ezacile kakhulu ukuze ugweme ukushintsha ubukhulu be-die orifice. Gcoba itheyiphu kusukela ngaphambili kuya ekugcineni kwendawo yokuphuma ukuze unciphise ukuncibilika kokungena emalungeni ethanga. Isifanekiso se-Pelletizer: Sichayeke ngokuqondile ekuncibilikeni kwezinga lokushisa eliphezulu kanye nokuhuzuka kwefiber yengilazi. Itheyiphu yomsebenzi osindayo ongu-0.25 mm noma ngaphezulu iyadingeka, futhi ilawulwa njengento esetshenziswayo evamile. Amaroli amafilimu e-Cast / ama-traction press rolls: I-Anti-stick futhi kulula ukuyihlanza. Itheyiphu ye-PTFE esekelwe nge-silicone ingasongwa kuma-roller, noma imikhono ye-fiberglass ye-PTFE enganamatheli ingamukelwa. Qinisekisa ukumelana nezinga lokushisa kwetheyiphu kufana nezinga lokushisa elingaphezulu kwerola uma ukushisisa kuhilelekile.
