He aha nā waiwai o ka carboxymyl cell?
Pane:ʻO CarboxyMyl cellousel cellulouse he mau mea likeʻole ma muli o kāna mau'āpana likeʻole o ka hoʻololi. ʻO ke kiʻekiʻe o keʻano,ʻikeʻiaʻo ia e like me ke kiʻekiʻe o ka hoʻopunipuni Ke hoʻopauʻia nā pūʻuluʻekoluʻekolu i ka pahu celilouse e pili ana i 0.4 h I ka hui hydroxyl e hoʻololiʻia e ka wai. Hiki ke hoʻopauʻia i ka wai. I kēia manawa, kapaʻia he 0.4 ke kīʻaha chedit maʻamau a iʻole ka manadi kalima coderial deculite) (kaomiʻana i ka helu 404-1.1.2.
Nā waiwai o CarboxyMyl cellulouse:
(1) He kīwī keʻokeʻo (a iʻole ka palaoa, kīwī),ʻehaʻeha, a heʻano kūlike a he alkaline paha. He maikaʻi maikaʻi a me ka mana o ka mana.
(2) Hiki ke hoʻohanaʻia kona hopena aqueous e like me kahi emulsifier o ka aila / wai wai a me keʻano wai / aila. Loaʻa iā ia ka hiki i ka hiki ke kōkua no ka aila a me ka wax, a he emulisi ikaika ikaika.
(3) I ka wā e hālāwai ai ka hopena i nā salala momona nui e like me keʻano he countride, cusric Eia nō naʻe, koe wale nō no ke alakaʻiʻana i keʻano, hiki ke hoʻopauʻia ma Sodium hydroxied, aʻo nā kālele e like me ka modila.
) E like me ka nānāʻana, i ka wā e loaʻa ai ka waiwai o ka pH i ka 2.5 No laila, hiki ke noʻonoʻoʻiaʻo PH 2.5 ma keʻano koʻikoʻi.
(5) No nā salts e like me calcium, magnerium a me ka papaʻaina,ʻaʻole e hoʻemiʻia ka viscopsity a me nā phosphate edta a me nā phosphate edta a me nā phosphate a me nā phosphate edta a me nā phosphate a me nā phosphate edta a me nā phosphate a me nā phosphate e hoʻopili ai.
(6) Heʻano nui loa keʻano ma ka viscosity o kāna hopena aqueous. ʻO ka viscoity e hōʻemi ana i keʻano e kū pono ana i ka wā e kū ai ka mahana, a me nā mea'ē aʻe. ʻO ke kūpaʻa o ka viscosity o ka hopena o ka hopena o ka mahana o ka mahana e like me ka loliʻoleʻana, akā hiki i ka viscosity ke hoʻomehana ma luna o 80 ° C no ka manawa lōʻihi. ʻO ka maʻamau,ʻaʻole iʻoi aku ka nui o ka mahana ma mua o 110 ° C, inā mālamaʻia ka mahana no 3 mau hola, e hoʻihoʻi hou i ka huakaʻi i kona kūlana mua; Akā i ka wā i hoʻomehanaʻia ka mahana i ka 120 ° C no 2 mau hola,ʻoiai ua hoʻihoʻiʻia ka mahana e 18.9%. . ^.
(7)ʻO ka waiwai nui e loaʻa i kahi mana o ka viscosity ma ka viscosity o kona hopena aqueous. ʻO ka maʻamau, i ka wā e hoʻokaʻawale ai ka ph o kahi solcosity haʻahaʻa haʻahaʻa mai ka neutral, he mau mea kūʻai akuʻo ia no keʻano Inā he ph o ka ph o kahi hopena kiʻekiʻe-viscosity kiʻekiʻe mai ka neutral, e emi ana kona viscosity. He expline koi.
) ʻO ka laʻana, ua kūpono ia me ka holoholona holoholona, Gum Arabiss, GLYCERIN a me SOLULON SORTAND. Ua kūpono hoʻi me ka wai aniani, polyvinyl all, urea-formaldehyde Resin, etc., akā, akā i kahi pae liʻiliʻi.
(9)ʻO ke kiʻiʻoniʻoni i hanaʻia e ka mālamalama ultraviolet no nā hola 100 no nā hola he 100 mau hola a iʻole brittleness.
(10) Heʻekolu mau hōʻailona Viscosity e koho ai e like me ka noi. No ka gypsum, hoʻohana i ka viscosity medium (2% o nā hopena kūpono ma 300-600mpa · nā mea kūʻai aku ma 2000mpar
)
(12)ʻAʻohe o Bucteria a me nā microorganisms i ka hopena o konaʻano pwder, akā ua loaʻa iā lākou kahi hopena o kāna hopena. Ma hope o ka hoʻohālikelikeʻana, e kūʻia ka viscosity e hoʻokuʻu a maloʻo. Ke hoʻohui nei i kahi nui kūpono o nā preservatives i mua hiki ke mālama i kona viscosity a pale i ka māmā no ka manawa lōʻihi. Loaʻa nā Preservatatives
Pehea ka maikaʻi o ka hydroxyproopyl mathylcelllulose e like me ka wai-wai e noho ana no ka binderdrite no ka bindertrite?
E pane:ʻO ka hydroxyproopsl miyylcelllose ka wai kiʻekiʻe-maikaʻi-e pono ai i ka nohoʻana o Gypsum Cypsum Cypsum. Me ka hoʻonuiʻana o nā manaʻo o ka hydroxyproopplolose. ʻO ka mālamaʻana o ka wai o ka wai gypsum e hoʻonui i ka wikiwiki. I ka wā e hoʻohuiʻia ai ka wai i ka wai i hoʻohuiʻia, ka hopena o ka wai e pili ana i ka waihona gypsum e pili ana i ka 68%. I ka manawa hea i kū ai ka nui o ka wai i ka helu o 0.15%, ka nui o ka wai e hiki ai i ka helu gypsum cemented hiki ke hōʻea i ka 90.5%. A me nā koi hou o ka wai o ka mokulele o lalo. ʻO ka dosage o ka wai-wai e noho ana ma mua o 0.2%, hoʻonui hou i ka dosage, a me ka nui o ka wai e hoʻonui ai i nā mea o Gypsum Comepsum. ʻO ka hoʻomākaukauʻana i nā kumuwaiwai plasterdite a Alshdite. ʻO ka hana kūpono o ka hydroxyproopsl methylcrelllous he 0.1% -0%.
He aha nā hopena likeʻole o ka celluloseʻokoʻa ma ka plaster o ka paris?
E pane:ʻO ka carboxymyl cellulouse a me ka mollunuse cellulose, akā he mea kūpono ke kaheʻana o ka paila o ka parist ʻO ka milll elthl hope loa he haʻawina maikaʻi loa no nā mea hana Gypsum e hoʻopili ai, a he nui wale nō ka'ōmaka, inā he nui ka haʻawina. ʻoi aku ka kiʻekiʻe ma mua o ka carboxymyl cellulouse. No kēia kumu,ʻo ka hapa nui o nā gypsum e hoʻopili ai i keʻano o keʻano o ka carbonusetl cellulouse. Ma kēia ala, hiki ke wikiwikiʻia ka hana o ka wai o ka lālani kīwī a me ka hoʻonuiʻana o ka maʻi kīʻaha o ka GyPSum
