Nau'in adhesives

I.Polyurethane m
Mai aiki sosai da iyakacin duniya. Yana da kyau kwarai mannewa sinadaran tare da tushe kayan dauke da aiki gas, kamar kumfa, filastik, itace, fata, masana'anta, takarda, tukwane da sauran porous kayan, kazalika da karfe, gilashin, roba, filastik da sauran kayan tare da santsi saman..

II.Epoxy guduro m
An ƙirƙira shi daga kayan tushe na resin epoxy, wakili na warkewa, diluent, totur da filler. Yana da kyakkyawan aikin haɗin gwiwa, aiki mai kyau, in mun gwada ƙarancin farashi da tsarin haɗin kai mai sauƙi.

III.Cyanoacrylic m
Yana buƙatar warkewa idan babu iska. Rashin hasara shi ne cewa juriya na zafi bai isa ba, lokacin warkewa yana da tsayi, kuma bai dace da rufewa tare da manyan gibba ba.

IV.Polyimide tushen m
Babban mannen iri mai juriya mai zafi tare da kyakkyawan juriya na zafi kuma ana iya amfani dashi akai-akai a 260 ° C. Yana da kyakkyawan aikin ƙarancin zafin jiki da rufi. Rashin hasara shi ne cewa yana da sauƙin hydrolyzed a ƙarƙashin yanayin alkaline.

V.Phenolic guduro m
Yana da kyakkyawan juriya na zafi, ƙarfin haɗin gwiwa, kyakkyawan juriya na tsufa da ingantaccen rufin lantarki, kuma yana da arha kuma mai sauƙin amfani. Amma kuma shine tushen warin formaldehyde a cikin kayan daki.

VI.Acrolein na tushen m
Idan aka shafa saman wani abu, sauran ƙarfi zai ƙafe, kuma damshin da ke saman abin ko kuma daga iska zai sa monomer ɗin ya yi saurin juye-juye na anionic polymerization don samar da sarka mai tsawo da ƙarfi, yana haɗa saman biyu tare.

VII.Anaerobic adhesives
Ba zai ƙarfafa lokacin da ake hulɗa da oxygen ko iska ba. Da zarar iska ta keɓe, haɗe tare da tasirin tasirin ƙarfe na ƙarfe, zai iya yin polymerize da ƙarfafa da sauri a cikin zafin jiki, samar da haɗin gwiwa mai ƙarfi da hatimi mai kyau.

VIII.Inorganic m
Yana iya jure duka babban zafin jiki da ƙananan zafin jiki kuma yana da ƙarancin farashi. Ba sauƙin shekaru ba, tare da tsari mai sauƙi da babban mannewa.

IX.Hot narke manne
Adhesive thermoplastic da ake shafa a cikin yanayin narkakkar sa'an nan kuma a ɗaure lokacin da aka sanyaya zuwa ƙaƙƙarfan yanayi. A cikin rayuwar yau da kullun, ana iya amfani da shi azaman abin ɗaure littafi.

Lokacin zabar manne, kuna buƙatar la'akari da dalilai kamar yanayin mannewa, yanayin warkarwa na m, yanayin amfani da tattalin arziki. Alal misali, don lokuttan da ke buƙatar ɗaukar kaya mafi girma, ya kamata a zaɓi kayan haɗin gine-gine tare da ƙarfin ƙarfi; don aikace-aikacen da ke buƙatar warkewa da sauri, adhesives tare da saurin warkewa ya kamata a zaɓi.

Gabaɗaya, adhesives suna taka muhimmiyar rawa wajen samar da masana'antu na zamani da rayuwar yau da kullun. Ba wai kawai sauƙaƙe tsarin haɗin kai da rage farashi ba, amma har ma inganta inganci da amincin samfuran. Tare da ci gaban kimiyya da fasaha da haɓaka wayar da kan muhalli, mannewa na gaba za su kasance masu dacewa da muhalli, inganci da ayyuka da yawa.

Bayan ɗan taƙaitaccen fahimtar menene manne da nau'in sa, wata tambaya na iya zuwa cikin zuciyar ku. Wane irin kayan aiki za a iya amfani da su tare da adhesives? Da fatan za a jira ku gani a labari na gaba.
