ʻO ka hoʻomaikaʻi ʻana o ka hydroxypropyl methylcellulose ma ka hoʻopaʻa ʻana a me ka plastering mortar.

No ka ʻōnaehana pale pale waho, ʻo ia ka mea maʻamau me ka mortar hoʻopaʻa o ka papa hoʻopulapula a me ka mortar plastering e pale ai i ka ʻili o ka papa insulation. Pono e maʻalahi ka hoʻoulu ʻana i kahi momona hoʻopaʻa maikaʻi, maʻalahi e hana, ʻaʻole pili i ka pahi, a he anti-sag maikaʻi. hopena, adhesion mua maikaʻi a pēlā aku.

ʻO ka hoʻopaʻa ʻana a me ka plastering mortar e pono ai i ka cellulose e loaʻa nā ʻano penei: encapsulation maikaʻi a me ka hana no nā mea hoʻopihapiha; kekahi ea entrainment rate, hiki ke hoʻonui i ka puka puka o ka mortar; manawa hana lōʻihi; ka hopena anti-sag maikaʻi A me ka hiki ke hoʻomaʻemaʻe no nā ʻili kumu like ʻole; maikaʻi ka paʻa o ka slurry, a mālama ʻia ke kūlike o ka slurry hui ʻia no ka manawa lōʻihi. Hiki iā Shandong "Chuangyao" brand hydroxypropyl methylcellulose ke hoʻokō i nā pono kumu o ka hoʻopaʻa ʻana a me ka plastering mortar applications.

ʻO ka Hydroxypropyl methylcellulose ka hana paʻa wai kiʻekiʻe ma ke kahua o ka hoʻopaʻa ʻana a me ka plastering mortar. Hiki i ka paʻa wai kiʻekiʻe ke hoʻomaʻemaʻe piha i ka sima, hoʻonui nui i ka ikaika paʻa, a i ka manawa like, hiki iā ia ke hoʻomaikaʻi pono i ka ikaika tensile a me ka ikaika shear. Hoʻomaikaʻi nui i ka hopena kūkulu a hoʻomaikaʻi i ka hana hana.

He mea nui ka Hydroxypropyl methylcellulose i ka hoʻopaʻa ʻana a me ka hoʻonui ʻana i ka ikaika i nā mea mortar insulation thermal, e maʻalahi ai ka pahū ʻana i ka lole, hoʻomaikaʻi i ka hana pono, a ʻoi aku ka pale ʻana i ka sag. ʻO ka manawa hana, hoʻomaikaʻi i ka shrinkage a me ka pale ʻana, hoʻomaikaʻi i ka maikaʻi o ka ʻili, hoʻomaikaʻi i ka ikaika pili.

I loko o ka wai a i ʻole nā ​​ʻano wai like ʻole like ʻole, hiki ke hoʻopuehu ʻia ka hydroxypropyl methylcellulose i loko o nā ʻāpana maikaʻi, hoʻokuʻu ʻia i loko o ka dispersion medium a hoʻoheheʻe ʻia, me ka ʻole o ka ua a me ka agglomeration, a loaʻa ka colloid pale a me nā hopena stabilizing. Hiki i ka hui Yao ke hoʻoponopono i ke kaʻina hana a mālama i ka manawa viscosity e like me nā pono o ka mea kūʻai.
