Zotsatira za kuwonjezera cellulose mu ufa wa putty

Tikamagwiritsa ntchito ufa wa putty, nthawi zambiri pamakhala mavuto ena, kotero sitikudziwa chifukwa chake. Ndikuganiza kuti payenera kukhala mitundu isanu ndi iwiri ya mavuto omwe nthawi zambiri amawonekera mu ufa wa putty!

Choyamba: Chitani mwachangu. Izi zikugwirizana kwambiri ndi kuwonjezera calcium ya phulusa ndi kuchuluka kwa madzi omwe amasungidwa mu ulusi, komanso zimagwirizana ndi kuuma kwa khoma.

Chachiwiri: kupeta ndi kuzunguliza. Izi zikugwirizana ndi kuchuluka kwa madzi omwe amasungidwa, zomwe zimachitika mosavuta ngati kukhuthala kwa cellulose kuli kochepa kapena kuchuluka kwa kuwonjezerako kuli kochepa.

Chachitatu: kuchotsa ufa. Izi zikugwirizana ndi kuchuluka kwa calcium yowonjezeredwa, ndipo zikugwirizananso ndi kuchuluka ndi ubwino wa cellulose yowonjezeredwa. Izi zimawonekera mu kuchuluka kwa madzi osungidwa mu chinthucho. Kuchuluka kwa madzi osungidwa ndi kochepa ndipo nthawi yokwanira ya calcium yosungunuka ndi madzi sikokwanira.

Chachinayi: Kutupa. Izi zikugwirizana ndi chinyezi chouma komanso kusalala kwa khoma, komanso zikugwirizana ndi kapangidwe kake.

Chachisanu: Nsonga ya pini imawonekera. Izi zikugwirizana ndi cellulose, yomwe ili ndi mphamvu zochepa zopangira filimu. Nthawi yomweyo, zonyansa zomwe zili mu cellulose zimagwirizana pang'ono ndi phulusa la calcium. Ngati yankholo ndi lalikulu, ufa wa putty udzawonekera ngati zotsalira za nyemba. Sungayikidwe pakhoma, ndipo ulibe mphamvu yogwirizana nthawi imodzi. Kuphatikiza apo, izi zimachitikanso ndi zinthu monga magulu a carboxyl omwe awonjezeredwa ku cellulose.

Six: Mapanga a mapiri ndi mabowo ang'onoang'ono amawonekera. Izi zikuonekeratu kuti zikugwirizana ndi mphamvu ya pamwamba pa madzi ya hydroxypropyl methylcellulose, koma mphamvu ya pamwamba pa madzi ya hydroxyethyl aqueous solution si yoonekeratu. Zingakhale bwino kuchita chithandizo chopepuka.

Zisanu ndi ziwiri: Putty ikauma, imakhala yosavuta kusweka ndikukhala yachikasu. Izi zikugwirizana ndi kuwonjezera calcium yambiri ya imvi. Ngati calcium ya imvi yochuluka kwambiri, kuuma kwa ufa wa putty kumawonjezeka ikauma. Kuuma kokha komanso kusasinthasintha komwe kungasweke mosavuta, makamaka ikagwiritsidwa ntchito ndi mphamvu zakunja. Imagwirizananso ndi kuchuluka kwa calcium oxide mu calcium ya imvi.

1. N’chifukwa chiyani ufa wa putty umachepa mukawonjezera madzi?

Cellulose ether imagwiritsidwa ntchito ngati chokhuthala komanso chosungira madzi mu putty. Chifukwa cha thixotropy ya cellulose yokha, kuwonjezera kwa cellulose mu ufa wa putty kumabweretsanso thixotropy mutawonjezera madzi mu putty. thixotropy iyi imachitika chifukwa cha kuwonongeka kwa kapangidwe ka zinthu zomwe zili mu ufa wa putty. Kapangidwe kameneka kamachitika pakapuma ndipo kamasweka pansi pa kupsinjika. Izi zikutanthauza kuti, kukhuthala kumachepa mukasakaniza, ndipo kukhuthala kumabwereranso mukayima chilili.

2. Kodi chifukwa chiyani putty imakhala yolemera pang'ono poikanda?

Pankhaniyi, kukhuthala kwa cellulose komwe kumagwiritsidwa ntchito nthawi zambiri kumakhala kokwera kwambiri. Opanga ena amagwiritsa ntchito cellulose 200,000 popanga putty. Putty yomwe imapangidwa mwanjira imeneyi imakhala ndi kukhuthala kwakukulu, kotero imamveka yolemera ikakanda. Kuchuluka kwa putty komwe kumalimbikitsidwa pakhoma lamkati ndi 3-5 kg, ndipo kukhuthala ndi 80,000-100,000.

3. N’chifukwa chiyani putty ndi matope opangidwa ndi cellulose okhala ndi kukhuthala komweko amamveka mosiyana m’nyengo yozizira ndi chilimwe?

Chifukwa cha kutentha kwa chinthucho, kukhuthala kwa chinthucho kumachepa pang'onopang'ono kutentha kukakwera. Kutentha kukapitirira kutentha kwa chinthucho, chinthucho chimachotsedwa m'madzi ndikutaya kukhuthala kwake. Kutentha kwa chipinda nthawi zambiri kumakhala kopitilira madigiri 30, zomwe zimasiyana kwambiri ndi kutentha kwa nthawi yozizira, kotero kukhuthala kumakhala kotsika. Ndikofunikira kusankha chinthu chomwe chili ndi kukhuthala kwakukulu mukamagwiritsa ntchito chinthucho nthawi yachilimwe, kapena kuwonjezera kuchuluka kwa cellulose, ndikusankha chinthu chomwe chili ndi kutentha kwakukulu kwa gel.
