Lokacin matsawa gyare-gyare na thermosetting robobi a cikicemented carbide molds, Dole ne a kiyaye su a wani zafin jiki da matsa lamba na wani lokaci don cikakken haɗin haɗin gwiwa da ƙarfafa su cikin sassan filastik tare da kyakkyawan aiki. Ana kiran wannan lokacin lokacin matsawa. Lokacin matsawa yana da alaƙa da nau'in filastik (nau'in guduro, abun ciki maras tabbas, da dai sauransu), siffar ɓangaren filastik, yanayin tsari na gyare-gyaren gyare-gyare (zazzabi, matsa lamba), da matakan aiki (ko don shayewa, pre-matsa lamba, preheating), da dai sauransu Yayin da zafin jiki na matsawa ya karu, filastik yana ƙarfafa da sauri kuma lokacin da ake buƙata ya ragu. Sabili da haka, sake zagayowar matsawa kuma zai ragu yayin da yawan zafin jiki ya karu. Tasirin matsa lamba na gyare-gyare akan lokacin gyare-gyaren ba a bayyane yake kamar yanayin zafin jiki ba, amma yayin da matsin lamba ya karu, lokacin matsawa kuma zai ragu kadan. Tun da preheating yana rage cikar filastik da lokacin buɗewa, lokacin matsawa ya fi guntu ba tare da preheating ba. Yawancin lokaci lokacin matsawa yana ƙaruwa yayin da kauri na ɓangaren filastik ya karu.
Tsawon lokacin matsawa na ciminti carbide mold yana da tasiri mai girma akan aikin sassan filastik. Idan lokacin matsawa ya yi ƙanƙara kuma filastik ba ta da ƙarfi sosai, bayyanar da kayan aikin injin ɗin na sassan filastik za su lalace, kuma sassan filastik za su sami naƙasu cikin sauƙi. Da kyau ƙara lokacin matsawa zai iya rage raguwar ƙimar sassa na filastik da inganta juriya na zafi da sauran kayan aikin jiki da na inji na ƙirar carbide. Duk da haka, idan lokacin matsawa ya yi tsayi sosai, ba kawai zai rage yawan aiki ba, har ma yana ƙara yawan raguwa na ɓangaren filastik saboda wuce haddi na resin, wanda zai haifar da damuwa, yana haifar da raguwa a cikin kayan aikin injiniya na ɓangaren filastik, kuma a lokuta masu tsanani, ɓangaren filastik na iya rushewa. Don robobin phenolic na gabaɗaya, lokacin matsawa shine mintuna 1 zuwa 2, kuma ga robobin silicone, yana ɗaukar mintuna 2 zuwa 7.
Menene ka'idoji don zaɓar kayan ƙirar carbide da aka yi da siminti?
1) Abubuwan da ake buƙata na ƙirar carbide ya kamata a cika su. Dole ne ya sami isasshen ƙarfi, taurin, filastik, tauri, da dai sauransu don saduwa da yanayin aiki, yanayin rashin nasara, bukatun rayuwa, aminci, da dai sauransu na ƙirar carbide.
2) Abubuwan da aka zaɓa ya kamata su sami kyawawan kayan sarrafawa bisa ga tsarin masana'antu daban-daban.
3) Ya kamata a yi la'akari da yanayin samar da kasuwa. Ya kamata a yi la'akari da albarkatun kasuwa da ainihin yanayin wadata. Yi ƙoƙarin magance matsalar cikin gida tare da ƙarancin shigo da kaya, kuma iri da ƙayyadaddun bayanai yakamata a mai da hankali sosai.
4) Carbide molds ya kamata ya zama mai tattalin arziki da ma'ana, kuma yayi ƙoƙarin amfani da kayan da ba su da tsada waɗanda suka dace da aiki da yanayin amfani.
