Alkyl Polyether: Zinthu Zopangira Mankhwala Zogwiritsidwa Ntchito Zambiri Zosiyanasiyana-1
Minda Yaikulu Yogwiritsira Ntchito
Mu makampani opanga mankhwala, ma polyether a alkyl amagwiritsidwa ntchito ngati zinthu zopangira thovu la polyurethane, zomatira, zomatira, ndi ma elastomer. Ma thovu a polyurethane amagwiritsidwa ntchito kwambiri mu mipando, matiresi, mipando yamagalimoto, ndi zipangizo zotetezera kutentha kwa nyumba. Ma glue ndi zomatira za polyurethane zimagwiritsidwa ntchito popanga nyumba, magalimoto, ndi zipangizo zamagetsi.
Mu makampani opanga mankhwala, ma alkyl polyethers amagwira ntchito ngati zinthu zowonjezerera komanso zosakaniza mu mankhwala, zomwe zimapangitsa kuti azisungunuka komanso kukhazikika. Amagwiritsidwanso ntchito popanga ma defoamers, surfactants, ndi zinthu zonyowetsa, zomwe zimagwiritsidwa ntchito kwambiri mu ma spray a pakamwa, m'mphuno, m'maso, m'makutu, ndi mu shampu.
Mu mafakitale opanga nsalu ndi mapepala, ma polyether a alkyl amagwiritsidwa ntchito ngati zofewetsa, zoletsa kutentha, komanso zonyowetsa. Amathandizira kufewa ndi mphamvu zoletsa kutentha kwa nsalu komanso kuonjezera ubwino wa mapepala komanso kugwira ntchito bwino popanga mapepala.
Mu gawo la zotsukira ndi zosamalira zaumwini, ma alkyl polyether amagwiritsidwa ntchito ngati ma surfactants ndi ma emulsifiers. Amasonyeza luso labwino loyeretsa, kutulutsa thovu, kukhazikika kwa thovu, kunyowetsa, ndi kusakaniza, lomwe limagwiritsidwa ntchito kwambiri mu shampu, kutsuka thupi, kutsuka m'manja, ndi sopo wochapira zovala.
Kuphatikiza apo, ma polyether a alkyl amagwiritsidwa ntchito ngati zochotsera mu mafuta, komanso ngati zoziziritsira ndi zodzola mu kukonza zitsulo.
Njira yopangira alkyl polyethers nthawi zambiri imaphatikizapo kuchiza zinthu zoyambitsa ndi zoyambitsa, kuchitapo kanthu kwa polymerization yotsegulira mphete, ndi njira zochizira pambuyo pake monga kuletsa, kulowetsa madzi m'thupi, kusefa, ndi kusungunula.

Powombetsa mkota
Mwachidule, ma polyether a alkyl, monga zipangizo zopangira mankhwala ambiri, amachita gawo lofunika kwambiri m'mafakitale osiyanasiyana. Sikuti amangowonjezera magwiridwe antchito ndi ubwino wa zinthu zokha komanso amathandizira chitukuko cha mafakitale amakono. Ndi kupita patsogolo kwaukadaulo kosalekeza, mwayi wogwiritsa ntchito ma polyether a alkyl udzakhala wokulirapo.
