PPDI tsantsa ce 1,4-Phenylene diisocyanate (PPDI), lambar CAS ita ce 104-49-4. PPDI ci-gaban wakili ne na warkarwa / sarƙoƙi don polyurethane (PU) thermoplastic elastomers. Abubuwan elastomers na tushen PPDI suna fasalta tare da kyakkyawan aiki mai ƙarfi. Babban fa'idar ita ce manyan ƙafafun da aka samar tare da PPDI na iya tsayawa ga zafin jiki mai yawa a ƙarƙashin aiki mai sauri da ci gaba. Don haka, ƙafafun tushen PPDI shine mafita mai kyau ga waɗanda ke buƙatar rayuwa mai tsayi, babban ƙarfin ɗaukar nauyi da buƙatun juriya mai zafi. Gabaɗaya, PU elastomers suna da kyau kwarai abrasion, tsagewa da yanke juriya idan aka kwatanta da roba na roba. Duk da PPDI da MDI suna da nau'ikan tsari iri ɗaya, tauri da kaddarorin modulus idan aka kwatanta da TODI, isocyanate yana da ƙarancin molar molar na polyol zuwa polyol a cikin PPDI. Ainihin, nau'ikan elastomers na nau'in PPDI sun fi sassauƙa fiye da nau'in MDI-na al'ada da nau'in elastomer na polyurethane na TODI. Daga cikin dukkanin elastomers na polyurethane, tushen PPDI an san su da ƙafafun da ke da matukar damuwa, watau tayoyin don matsuguni, motoci da jiragen sama; rollers jagora, ƙafafun don inji; babban gudun skate rollers da sauransu. A takaice, nau'in elastomer na nau'in PPDI shine mafi kyawun zaɓi don aikace-aikacen mafi ƙanƙanta abrasion da Mafi girman zafin jiki. A zamanin yau, PPDI curing wakili ne yadu amfani a cikin TPU-samfurori a matsayin babban sarkar extender, da kuma aikace-aikace ci gaba da fadada, ciki har da O-zobba, na'ura mai aiki da karfin ruwa hatimi, hada guda biyu taurari da allo bugu squeegee ruwan wukake.
Fa'idodi don fa'idodinsa na ban mamaki na zafi, abrasion, tsagewa da yanke juriya, ana amfani da elastomers na tushen PPDI akan masana'antu waɗanda ke buƙatar ƙarancin nakasu, ayyuka masu dorewa. PPDI shine babban mai kunnawa a cikin TPU (thermoplastic polyurethane elastomer). Na'ura mai aiki da karfin ruwa hatimi, wipers, piston hatimi, O-zobe, sanda hatimi, pulleys wanda ya nema ga zafi juriya da kuma matsa lamba juriya su ne wasu muhimman filayen PPDI curing wakili. Kada a ambaci tayoyin forklifts, ababen hawa, inji, jiragen sama da jakunkuna, ƙafafu, rollers na jagora don abubuwan da ke dagula abubuwa waɗanda su ne sauran nau'in nau'in elastomers na nau'in PPDI.
Shiryawa: 20kg, 40kg, 50kg / baƙin ƙarfe drum.
Adana da sufuri: PPDI yana da matukar damuwa ga danshi. Ruwa yana amsawa tare da duk diisocyanates don samar da abubuwan urea marasa narkewa. Kada ku sanya PPDI tare da abinci kuma ku guji fallasa a cikin yanayi sama da 30 ℃. Bayan amfani, dole ne a rufe murfin nan da nan idan akwai rashin aiki. Ƙarƙashin yanayin waje masu dacewa, PPDI tana aiki na tsawon watanni shida aƙalla tare da tasiri daga ranar da aka kawo ta.
