1. Roba ta halitta
Robar halitta tana da sauƙin samun plasticity. Danko mai dorewa da ƙarancin danko na robar maleic ba shi da ɗanko na farko kuma gabaɗaya ba ya buƙatar a yi masa robobi. Idan danko na Mooney na wasu nau'ikan manne na yau da kullun ya wuce digiri 60, har yanzu yana buƙatar a yi musu robobi. Lokacin amfani da mahaɗin ciki don yin plasticizer, lokacin yana kimanin mintuna 3-5 lokacin da zafin jiki ya kai sama da digiri 120. Lokacin ƙara plasticizers ko plasticizers, yana iya rage lokacin plasticization sosai da inganta tasirin plasticization.
2. Styrene-butadiene
Gabaɗaya dai, danko na Mooney na Styrene-butadiene galibi yana tsakanin 35-60. Saboda haka, Styrene-butadiene kuma ba ya buƙatar plasticization. Amma a zahiri, bayan plasticization, ana iya inganta watsewar sinadarin mahaɗin, wanda ke taimakawa wajen inganta ingancin samfur. Musamman ga samfuran robar soso, Styrene-butadiene yana da sauƙin kumfa bayan plasticization, kuma girman kumfa iri ɗaya ne.
3. Polybutadiene
Polybutadiene yana da yanayin kwararar sanyi kuma ba shi da sauƙi a inganta tasirin plasticization. A halin yanzu, an sarrafa danko na Mooney na Polybutadiene da aka saba amfani da shi a cikin kewayon da ya dace yayin polymerization, don haka ana iya haɗa shi kai tsaye ba tare da plasticization ba.
4. Neoprene
Ba sai an yi amfani da sinadarin Neoprene a matsayin robobi ba, amma saboda ƙarfinsa, yana da amfani wajen aiki. Zafin da ke cikinsa yawanci yana tsakanin 30 ℃ -40 ℃, wanda hakan yana da sauƙin mannewa idan ya yi yawa.
5. Robar Ethylene propylene
Saboda cikakken tsarin babban sarkar robar Ethylene propylene, yana da wuya a haifar da tsagewar kwayoyin halitta ta hanyar amfani da robobi. Saboda haka, yana da kyau a haɗa shi don ya sami danko mai dacewa da Mooney ba tare da buƙatar yin ƙera ba.
6. Robar Butyl
Robar Butyl tana da tsari mai ƙarfi da laushi na sinadarai, ƙaramin nauyin ƙwayoyin halitta da kuma babban ruwa, don haka tasirin robar da ake amfani da ita a injiniya ba shi da kyau. Ana iya haɗa robar Butyl mai ƙarancin danko na Mooney kai tsaye ba tare da robar da ake amfani da ita ba.
7. Robar Nitrile
Robar Nitrile tana da ƙaramin roba, ƙarfin tauri da kuma yawan zafi yayin yin roba. Saboda haka, yawanci ana amfani da ƙarancin zafi, ƙarancin ƙarfi da kuma roba mai sassauƙa a cikin injin niƙa don cimma sakamako mai kyau. Bai kamata a saka roba a cikin injin niƙa na ciki ba. Ganin cewa robar Nitrile mai laushi tana da wani nau'in roba, ana iya haɗa ta kai tsaye ba tare da tace roba ba.
