Cellulose ether ndi polymer yopanga iyaic-yopanga, yomwe ndi yosungunuka madzi ndi solveleble. Imakhala ndi zovuta zosiyanasiyana m'mafakitale osiyanasiyana. Mwachitsanzo, m'magawo omanga mankhwala, ili ndi zotsatirazi:
① Madzi osungirako ntchito, ②thickener, ③levevel, ③levevel, ③fil kupanga katundu, ⑤bindar
Mu mankhwala a Polyvinyl chloride, ndi emulsiferier ndi obalalika; M'makampani opangira mankhwala, ndi wowonda komanso wodekha komanso wowongolera amatulutsa magwiridwe ake, ndi zina zambiri. Kenako, ndidzayang'ana pa kugwiritsa ntchito ndi ntchito ya ethel ether zinthu zosiyanasiyana zomangamanga.
mu utoto wa mochedwa
Mu makampani opanga ma tepi a latex, kusankha hydroxethyl cellulose, zomwe zikufanana ndi ma visn a visnce omwe ali 30000-500000000, ndipo mankhwalawa nthawi zambiri amakhala 1.5 ‰ -2 ‰. Ntchito yayikulu ya hydroxyethyl mu utoto wa latex ndi kunenepa, muchepetse kufalikira kwa pigment, kukhazikika kwa zigawozo, ndikuwonjezera mamasukidwe a zomangamanga: Hydroxyethyl cellulose ndiyofunika kugwiritsa ntchito. Itha kusungunuka m'madzi ozizira ndi madzi otentha, ndipo sizikhudzidwa ndi mtengo wa pH. Itha kugwiritsidwa ntchito bwino pakati pa PIMU 2 ndi 12. Njira zogwiritsira ntchito ndizotere:
I. Onjezani mwachindunji kupanga
Panjira imeneyi, hydroxethyl cellulose yochedwa kuchedwa kuyenera kusankhidwa, ndipo hydroxyethyl cellulose wokhala ndi mphindi zopitilira 30 amagwiritsidwa ntchito. Masitepewo ndi awa: Zipangizo zonse za granlar zimanyowa - zina zowonjezera komanso zowonjezera zowonjezera, etc.
2. Kukhala ndi zakumwa zakumwa za amayi kuti zigwiritse ntchito pambuyo pake
Njirayi imatha kusankha mtundu wa nthawi yomweyo, ndipo ali ndi anti-Phulitsalew zotsatira cellulose. Ubwino wa njirayi ndikuti umasinthasintha kwambiri ndipo amatha kuwonjezeredwa mwachindunji penti ya latex. Njira yokonzekerayo ndi yofanana ndi masitepe ① - ④.
3. Pangani kukhala mu porridge kuti mugwiritse ntchito pambuyo pake
Popeza ma sodic okhazikika ndi osauka (osasunthika) a hydroxyethyl, izi sol sol angagwiritsidwe ntchito kupanga phala. Ogwiritsa ntchito solic yemwe amapezeka kwambiri ndi zakumwa zopangidwa ndi utoto wa utoto wa latex, monga ethylene glycol, Propylene Glycol, ndi othandizira mafilimu (monga ma mestylene glycol). Porridge hydroththyl cellulose imatha kuwonjezeredwa mwachindunji penti. Pitilizani kusuntha mpaka kusungunuka kwathunthu.
mwakuti
Pakadali pano, m'mizinda yambiri m'dziko langa, malo osokoneza bongo komanso ophatikizika amayamikiridwa ndi anthu. Imapangidwa ndi acetal zomwe zimamwa vinyl mowa komanso formaldehyde. Chifukwa chake, zinthuzi zimachotsedwa pang'onopang'ono ndi anthu, ndipo mankhwala opanga a Eleal Ether amagwiritsidwa ntchito m'malo mwa izi. Ndiye kuti, pakukula kwa zida zomangira zomangira, cellulose ndi zinthu zokhazokha.
M'kunjenjemera ndi madzi, amagawidwa m'mitundu iwiri: ufa wowuma ndi phala. Mwa mitundu iwiri iyi ya putty, methyl cellulose ndi hydroxypropyl methyl iyenera kusankhidwa. Kutanthauzira kwa Viscty kuli pakati pa 40000-75000000cps. Ntchito zazikuluzikulu za cellulose ndi kusungidwa kwamadzi, kulumikizana ndi kuphatikizika ndi mafuta.
Popeza njira zopangira zosiyanasiyana ndizosiyana, ena ndi a calcium, sitacium, simenti yoyera, etc., etc.ction ya cellose mu Mitundu iwiri ndi yosiyananso. Ndalama zomwe zimawonjezeredwa pafupifupi 2 ‰ -3 ‰.
