ʻO ke kuleana o ka hydroxypropyl starch ether i ka mortar

Hoʻopuka pinepine ka moʻokāki WeChat i nā ʻike kiʻekiʻe e like me ka ʻike loea, cellulose maka kumu kumu kūʻai, nā ʻano mākeke, nā hoʻemi, a me nā mea ʻē aʻe, a hāʻawi i nā ʻatikala ʻoihana e pili ana i ka pauka putty, mortar a me nā mea hana kemika hana ʻē aʻe! E hahai mai iā mākou!

Introduction to Starch Etera

ʻO nā mākoi maʻamau a hoʻohana mau ʻia, ʻo ia ka starch potato, starch tapioka, starch kulina, starch palaoa, a me ka starch cereal me ka momona a me ka protein ʻoi aku ka nui. ʻOi aku ka maʻemaʻe o nā mākoki hua e like me ka ʻuala a me ka mākū tapioka.

ʻO ka starch kahi pūhui macromolecular polysaccharide i haku ʻia me ka glucose. ʻElua ʻano molekole, laina a me nā lālā, i kapa ʻia ʻo amylose (maʻiʻo 20%) a me amylopectin (ma kahi o 80%). I mea e hoʻomaikaʻi ai i ka hoʻohana ʻana i nā waiwai o ka starch i nā mea kūkulu hale, hiki ke hoʻololi ʻia e nā ʻano kino a me nā ʻano kemika e hana i kona mau waiwai i kūpono no nā pono o nā mea kūkulu hale no nā kumu like ʻole. Hydroxypropyl starch ether

ʻO ke kuleana o ka starch ether i ka mortar

No ke ʻano o kēia manawa o ka hoʻonui ʻana i ka ʻāpana tile, hiki i ka hoʻohui ʻana i ka starch ether ke hoʻomaikaʻi i ka pale ʻana i ka paheʻe o ka tile adhesive.

hola wehe ʻia

No nā tile tile, hiki iā ia ke hoʻokō i nā koi o nā tile kūikawā kūikawā (Class E, 20min i hoʻonuiʻia i 30min a hiki i ka 0.5MPa) e hoʻonui i ka manawa wehe.

Hoʻomaikaʻi ʻia nā waiwai o ka ʻili

Hiki i ka starch ether ke hana i ka ʻili o ka base gypsum a me ka mortar sima, maʻalahi e hoʻopili, a he hopena hoʻonaninani maikaʻi. He mea koʻikoʻi loa ia no ka hoʻopalapala ʻana i ka momi a me ka ʻāpana lahilahi o ka mīkini hoʻonaninani e like me ka putty.

Mechanism of action of starch ether

Ke hoʻoheheʻe ʻia ka starch ether i ka wai, e hoʻopuehu ʻia i loko o ka ʻōnaehana sima. No ka loaʻa ʻana o ka molela starch ether i kahi ʻano pūnaewele a hoʻopiʻi maikaʻi ʻia, e hoʻopaʻa ʻia i nā ʻāpana sima maikaʻi a lilo i alahaka hoʻololi e hoʻopili ai i ka sima, no laila e hāʻawi ana ʻO ka waiwai nui o ka slurry hiki ke hoʻomaikaʻi i ka anti-sag a i ʻole anti- hopena paheʻe.

ʻO ka ʻokoʻa ma waena o ka starch ether a me ka cellulose ether

(1) Hiki i ka starch ether ke hoʻomaikaʻi maikaʻi i ka hana anti-sag a me ka anti-slip o ka mortar, ʻoiai ka cellulose ether e hiki ke hoʻomaikaʻi wale i ka viscosity a me ka paʻa wai o ka ʻōnaehana akā ʻaʻole hiki ke hoʻomaikaʻi i ka hana anti-sag a me ka anti-slip.

(2) mānoanoa a me ka viscosity

ʻO ka mea maʻamau, ʻo ka viscosity o cellulose ether ma kahi o ʻumi tausani, ʻoiai ʻo ka viscosity o ka starch ether he mau haneli a he mau tausani, akā ʻaʻole ia he manaʻo ʻaʻole maikaʻi ka waiwai mānoanoa o ka starch ether i ka mortar e like me ka cellulose ether. a ʻokoʻa ke ʻano mānoanoa o nā mea ʻelua.

(3) Ke hoʻohālikelike ʻia me cellulose, hiki i ka starch ether ke hoʻonui nui i ka waiwai hua mua o ka tile adhesive, a laila e hoʻomaikaʻi ai i ka hana anti-slip.

(4) Hoʻokomo ea

Loaʻa i ka cellulose ether kahi waiwai e hoʻopili ai i ka ea, ʻoiai ʻo ka starch ether ʻaʻohe waiwai e komo i ka ea.

(5) ʻO ka hoʻolālā molecular cellulose ether

ʻOiai ʻo ka starch a me ka cellulose i haku ʻia i nā molekole glucose, ʻokoʻa kā lākou ʻano hana. Hoʻonohonoho ʻia nā molekole glucose a pau i ka starch ma ka ʻaoʻao hoʻokahi, ʻoiai ʻo ka cellulose ka mea kūʻē. ʻO kēlā me kēia ʻaoʻao pili ʻO ka hoʻonohonoho ʻana o nā molekole glucose he kūʻē, a ʻo kēia ʻokoʻa hoʻonohonoho hoʻi e hoʻoholo i ka ʻokoʻa o nā waiwai o ka cellulose a me ka starch.

Ka hopena: Ke hoʻohana ʻia ka cellulose ether a me ka starch ether i ka hui pū ʻana, hiki ke loaʻa kahi hopena synergistic maikaʻi. Ua hōʻike nā hoʻokolohua i ka hoʻohana ʻana i ka starch ether e hoʻololi i ka 20% -30% o ka cellulose ether i loko o ka mortar ʻaʻole hiki ke hōʻemi i ka mana paʻa wai o ka ʻōnaehana mortar, a hiki ke hoʻomaikaʻi maikaʻi i ka hiki ke anti-sag a me ka anti-slip.
