Momwe mungasinthire kumverera kolemetsa kwa dzanja la putty scraping

funso:

Putty akumva kulemera

Pakumanga putty, anthu ena amakumana ndi vuto lomwe dzanja limamva lolemera.Kodi chifukwa chenichenicho ndi chiyani?Kodi zingatheke bwanji?

Zifukwa zomwe zimachititsa kuti putty amve kulemera ndi:

1. Kugwiritsa ntchito molakwika mawonekedwe a viscosity wa cellulose ether:

Pachifukwa ichi, kukhuthala kwa cellulose ether nthawi zambiri kumakhala kokwera kwambiri, ndipo putty yopangidwa imakhala yolemetsa panthawi yopukutira;

Chifukwa china ndi chakuti pakumanga m'chilimwe, kugwiritsa ntchito hydroxypropyl methylcellulose ether ndi kukana kutentha kwapamwamba kungapangitse putty kutaya kukhuthala, zomwe zidzakhudza zomangamanga.

2. Chiŵerengero cholakwika kapena fineness wa ufa:

Nthawi zambiri, pali zinthu zambiri zopangira ma gelling, kapena fineness ya chodzaza chosankhidwa ndichabwino kwambiri, chomwe chimakonda kumamatira ku mpeni;

N'zothekanso kuti kuchepetsa ndalama, palibe kapena zochepa zina kuwonjezera dzanja kumva anawonjezera, monga wowuma ethers ndi thixotropic lubricants.

Njira zowonjezera 1

Zoyenera zopangira zopangira ndi kusankha fineness

Ubwino wazinthu zonse zopangira zitha kuwongoleredwa pa 150-200 mesh, ndipo kufinya kwa chodzaza nthawi zambiri kumakhala ma mesh 325, osati abwino kwambiri;

Kuchuluka kwa ufa wa polyvinyl mowa sikudutsa 6%;

M'pofunikanso kuphunzira kuchepetsa kuchuluka kwa inorganic cementitious zipangizo.Nthawi zambiri, ndikwanira kuwongolera simenti pa 28% -32%, ndikugwiritsa ntchito zowonjezera kuti zikule bwino ntchito yake.

Njira yowonjezera 2

Sankhani cellulose ether yoyenera

Nthawi zambiri, timalimbikitsa hydroxyethyl methyl cellulose ether ndi ntchito yabwino, yomwe imakhala ndi kutentha kwapamwamba kwambiri ndipo imatha kusinthidwa kuti ikhale yomanga chilimwe ndikuchepetsa ndalama zosinthanitsa ndi chisanu ndi chilimwe;

Chinsinsi ndicho kusankha ether ya cellulose yokhala ndi mamasukidwe oyenera.Nthawi zambiri, ether ya cellulose yokhala ndi kukhuthala kwa 80,000 mpaka 100,000 ndiyokwanira pa ufa wa putty, koma kuchuluka kwa ether ya cellulose yowonjezeredwa kuyenera kutsimikiziridwa kudzera muzoyesa zomveka zomanga!

Njira zowonjezera 3

Onjezani zowonjezera kuti mumve bwino m'manja

Pomaliza, tikhoza kuganizira kuwonjezera wowuma etere kapena thixotropic lubricant (bentonite) kusintha kumverera kwa matope;

Kumbukirani: kuphatikiza njira zasayansi ndiye chinsinsi chothetsera vutoli!
