Kuyesa ndi utoto wamba waku America

Gulu lathu tsopano lili mu gawo lachitukuko chofulumira, ndipo zofunikira za liwiro ndizokwera kwambiri. Choncho, kufunikira kwa magalimoto ndi opanga kwawonjezeka. Pamene kuchuluka kwa magalimoto pamsewu ukuwonjezeka, kuvala pamsewu kumawonjezekanso.

Ndi chitukuko cha teknoloji, mchenga wa galasi umagwiritsidwa ntchito kwambiri; mwachitsanzo, m'makampani opanga mankhwala, mchenga wa galasi nthawi zambiri umagwiritsidwa ntchito pokongoletsera zinthu zamagalasi. M'zaka zaposachedwapa, ndi kusintha kwa moyo wa anthu, anthu ambiri amamvetsera kwambiri zofunikira za zokongoletsera; pansi pazimenezi, kugwiritsa ntchito zipangizo zoterezi kwakonzedwanso.

Tinthu tating'onoting'ono ta Ceramic timasiyana ndi miyala ya asphalt wamba. Tinthu tating'onoting'ono ta ceramic ndi mtundu watsopano wa zinthu zomwe zimagwiritsidwa ntchito m'maiko osiyanasiyana. Izi zimagwiritsidwa ntchito kwambiri popanga zikwangwani pamisewu yayikulu, ma eyapoti, njanji za ndege, masitima apamtunda, masitima apamtunda, malo okwerera mabasi, malo oimikapo magalimoto, mapaki, mabwalo, masukulu ndi mahotela, nyumba zamaofesi, ndi zina zambiri.

Mapangidwe a utoto wotentha wa thermoplastic

Ma rosin resin acids amakhala ndi majini amitundu iwiri ndi carboxyl-active, okhala ndi ma conjugated double bond komanso machitidwe agulu la carboxyl. Kuphatikiza pa kukhala tcheru ku oxidation ndi isomerization, rosin imakhalanso ndi machitidwe awiri ogwirizana monga disproportionation, hydrogenation, kuwonjezera, ndi polymerization.Pa nthawi yomweyo, imakhala ndi machitidwe a carboxyl monga esterification, alcoholization, mchere, decarboxylation, ndi aminolysis. .
