Sichithachithekile PTFE Resin Intshayelelo
Ukuqulunqwa kwabahlakazekileyo PTFE I-resin iphantse ibe yi-100% PTFE (polytetrafluoroethylene) intlaka. Sichithachithekile PTFE resin iveliswa kusetyenziswa indlela yokusasazwa kwaye ifanelekile kwi-paste extrusion, eyaziwa ngokuba yi-paste extrusion-grade PTFE intlaka. Ineempawu ezahlukeneyo ezibalaseleyo ze PTFE i-resin kwaye inokucutshungulwa ibe bubude obuqhubekayo beetyhubhu ezinodonga olucekethekileyo, iintonga, ucingo kunye nokufakelwa kwentambo, iigaskets, nokunye.
Intshayelelo yeNkqubo yeMveliso
Abachithachithiweyo PTFE resin powder icinezelwe kwangaphambili ibe imilo sheet usebenzisa umatshini rolling, kwaye ke ingena kumatshini vulcanizing apho ifudunyezwe amashumi aliqela imizuzu kwi 200-370 ° C kunye 100 ukuya 1000 atmosphere yoxinzelelo ukuvelisa izinto sheet polytetrafluoroethylene ukuba. uyaqonda kwaye uyaqonda. Abachithachithiweyo PTFE i-resin powder nayo inokongezwa ngokuthe ngqo kwi-mold kwaye iveliswe kuyo nayiphi na imilo PTFE imveliso phantsi koxinzelelo lwe-200-370 ° C kunye ne-100-1000 ye-atmospheres yoxinzelelo. Ukuba i-1% ye-wax yeparafini idityaniswe kwizihlakaniphi PTFE i-resin, inokuqengqeleka ngokuphindaphindiweyo ukuvelisa PTFE itheyiphu yofakelo lombhobho. Iringi yepiston yecompressor enkulu enobubanzi obuyi-1050 millimeters eyenziwe kuyo inobomi obude obuqhubekayo benkonzo. Eyona ndlela iphambili yokusebenza kwayo “yinkqubo yesibini yokusebenza” (engenziwanga ngokupheleleyo, ipholymerized ngokupheleleyo ngexesha lokusetyenzwa kwesibini), enokusetyenziswa ukwenza nayiphi na i-polymerized. PTFE iinxalenye.
Iimpawu zokuSasazwa PTFE resin
Abachithachithiweyo PTFE yintlaka engumgubo enozinzo olugqwesileyo lobushushu, ukungangeni kweekhemikhali okubalaseleyo, iipropathi zombane eziphezulu, kunye ne-coefficient ephantsi yokukhuhlana. Ezi mpawu zibalaseleyo zenza kube lukhetho olufanelekileyo kwizicelo ezahlukeneyo.
Ukusetyenziswa kunye neempawu
Ezi mveliso ziyilelwe ukuba zixutywe kunye nolwelo lwe-organic olusetyenziswa njengezongezo, kwaye lunokusetyenzwa kusetyenziswa ubuchule obufana ne-calendering kunye ne-extrusion. Zikulungele ukuvelisa iintonga ezinobungakanani obuncinci, iityhubhu ezinodonga oluncinci, iileyile zokugquma ikhebula, kunye namabhanti angafakwanga kwimiba ephakathi ukuya ephantsi yoxinzelelo kunye namaxabiso aphakathi ukuya aphantsi.
Uchungechunge lwe-SFN lubandakanya i-SFN-1, i-SFN-3, i-SFN-A, kunye ne-SFN-5A. Uluhlu lwe-SFN lunikeza ukuchasana kweekhemikhali ezigqwesileyo, kuquka ukuchasana ne-acids eqinile, i-alkali, kunye ne-oxidizing agents. Babonisa ubushushu obubalaseleyo kunye nokumelana nokubanda, kunye nomgangatho wokusetyenziswa kwexesha elide lobushushu obuphakathi kwe -190 ° C ukuya +250 ° C. Ezi mveliso zinee-coefficients ezisezantsi zokukhuhlana, iipropathi ezibalaseleyo zokuzithambisa, kunye nokusebenza kombane okuphezulu. Abachatshazelwa yiqondo lokushisa okanye ukuphindaphinda, kwaye musa ukunamathela, ukufunxa umswakama, ukutshisa, okanye ukufumana ukuguga okubalulekileyo phantsi kweemeko ze-atmospheric. Isetyenziswa kakhulu kushishino lweekhemikhali, oomatshini, i-petroleum, amayeza, i-elektroniki, i-optics kunye namanye amasimi.
Abachithachithiweyo PTFE intlaka inokohlulwa ibe ziindidi ezimbini: umgubo kunye nolwelo olugxininisiweyo lokusasazwa. Phakathi kwazo, i-resin ye-dispersion powder, emva kokuxutywa kunye nenani elithile lezongezo (ezifana ne-ether ye-petroleum) kunye nezihlungi (ezifana nomgubo we-quartz), zifanelekile ukubunjwa koxinzelelo lweemveliso ezinqabileyo, ezifana neengcingo kunye neentambo. Isetyenziswa ngokubanzi kushishino lwangoku lweengcingo kunye nentambo. Intlaka yosasazo engumgubo inokucinezelwa ukuze imile kwaye emva koko iqengqeleke ibe yifilim ebhityileyo (ekwabizwa ngokuba yiteyiphu) ukuze kugqunywe okanye kugqunywe iingcingo ezicolekileyo ezidayameni zocingo. Ipolytetrafluoroethylene concentrated dispersion liquid isetyenziswa ikakhulu ukugquma umphezulu wezinto ezirhabaxa (ezifana ne asbestos kunye ne glass fiber weaving) kunye neebheringi zentsimbi ezenziwe ngomgubo wemetalurgy method. Umaleko wokulukwa kwefibre yeglasi ye PTFE i-electromagnetic wire kunye ne-high-temperature resistant wire iqatywe nge-concentrated dispersion liquid ye-polytetrafluoroethylene.
