Ubumenyi bwa hydroxypropyl selile

Intangiriro Kuri HydroxyPropyl Methyl
HydroxyPropyl Methylcellse, uzwi kandi nka Hypromellose na hydroxypropyl methyl, ikozwe muri selile nziza cyane nkibikoresho fatizo, byangiritse cyane mubihe bya alkaline. HPMC ni ifu yera, itaryoshye, impuhwe, idafite uburozi, idahinduka rwose mumubiri wumuntu kandi itagaragara mumubiri. Ibicuruzwa birashonje mumazi, ariko bidahwitse mumazi ashyushye. Igisubizo cyamazi ni ikintu kitagira ibara rifite ibara. HPMC ifite ubwinshi, bugenda, bubahiriza film, ikwirakwizwa, gukwirakwiza ubushuhe, ubuvuzi, imiti, imitungo, inkambi, inkambi, imiti no gutunganya imiti.

1. Ibikubiye muri calcium ya gray calcium hamwe na kaburimbo idakwiye ya cao na ca (OH) 2 mumibura ya Gray izatera igihombo cya powder. Niba ifite aho ihuriye na HPMC, niyaba imuhirizwa rya HPMC rikennye, izanakaza igihombo cyafashwe. Ifu ibuze ifu ya Putty ijyanye na hydroxyproppopyl methylcellse? Ifu yo gutakaza ifu ya Prowty ifitanye isano ahanini nubwiza bwa calcium ya Ash, kandi ntaho ihuriye na HPMC.

2. Imikorere yingenzi ya HydroxyPropyl Methylcellse nifungwa amazi, ikurikirwa no kubyimba. Muri ifu ya Putty, igihe cyose ihohoterwa rishingiye ku mazi ari ryiza kandi ko bigaragara ko ari hasi (70.000-80.000), birashoboka. Birumvikana ko hejuru cyane viscosiya, gusubizwa amazi meza. Iyo visosity irenze 100.000, urubyiruko ruzagira ingaruka ku kugumana amazi. Ntabwo akiri byinshi.

Ni ubuhe buryo bwa hydroxyproppopyl methylcellse (HPMC)?

Powett ifu muri rusange yubura 100.000, kandi ibisabwa kuri minisiteri biri hejuru, kandi 150.000 Yuan irasabwa kugirango ikoreshwe byoroshye.

3. Ni ibihe bikoresho by'ibanze bya hydroxypropyl methylcellse? Ibikoresho nyamukuru bya hydroxypropyl methylcellse (HPMC): Ipamba yatunganijwe, umuswa wa methic, aside, aside, aside, Isopropanol, nibindi

4. Niyihe mpamvu yumunuro wa HydroxyPropyl Methylcellse? HydroxyPropyl methylcellse yakozwe nuburyo bworoshye bukoresha toluene na isopropanol nkuko bitanga. Niba gukaraba atari byiza cyane, hazabaho impumuro zisigaye.

5. Umwe ufite ubushyuhe bwinshi afite igumana ryamazi, ugereranije (ntabwo rwose), kandi Umwe ufite ubutwari bwo hejuru akoreshwa neza muri sima. Nibihe bipimo nyamukuru bya tekiniki? HydroxyPropyl Ibirimo no mu rubyiruko, abakoresha benshi bahangayikishijwe n'ibi bipimo byombi.

Ese ibintu bya eflorescence muri minisiteri bijyanye na hydroxyproppopyl methylcellse?

Hashize igihe, umukiriya yavuze ko ibicuruzwa byari bifite eflorescence, kandi yakoraga gutera. Kurasa: Imikorere nyamukuru ni ugutwikira inyuma, rougren, no kongera amarangamutima hagati yurukuta nuburyo bwo hejuru. Koresha bike cyane, gusa bitera urukuta ruto kurukuta. Hano hari ishusho ya effloresceon phenomenon ko umukiriya yanyohereje: shushanya icyambere nuko rwose ntabwo arimpamvu ya hydroxypropyl methylcellse ntabwo ihuye nibintu byose mumurongo wintanga. Kandi phenomenon yo muri efflorescence ni: beto isanzwe irasenyutse, iyo ihuye numwuka cyangwa ubushuhe bwa kion), kandi ubushyuhe bwa kera bwa Alkaline), kandi ubushyuhe bwa alkaline), kandi ubushyuhe bwa alkaline), niyishyushye alkaline hydroxide iterwa nurukuta. Hamwe no guhumeka buhoro buhoro, hydroxide iterwa no hejuru ya sima zifatika, itera icyuma cyijimye mugihe irangi cyangwa irangi ryazamuwe kandi ntizishyirwaho, no gukuramo, no gukuramo bizabaho. Iyi nzira yitwa "Pan-Alkali". Ntabwo rero Ubiquine yatewe na HydroxyPropyl Methylcellse

The customer also mentioned a phenomenon: the sprayed grout he made will have pan-alkaline phenomenon on the concrete wall, but will not appear on the fired brick wall, which shows that the silicon in the cement used on the concrete wall Salts (strongly alkaline salts) are too high. Efflorescence iterwa no guhumeka amazi yakoreshejwe mugutera gutera. Ariko, nta guserwa kurukuta rw'amatafari yamatafari kandi nta eflorescence izabaho. Ikintu rero cyo muri efflorescence ntaho bihuriye no gutera.

Igisubizo:

1. Ibirimo byangiza sima shingiro bigabanuka.

2. Koresha umugongo wo kurwanya alkali, igisubizo cyinjira mumabuye kugirango uhagarike capillary, kugirango amazi, umunyu ntashobora kwinjira, kandi akata inzira ya pan-alkaline phenomenton.

3. Irinde kwinjira mumazi, kandi ntukamijagire amazi menshi mbere yo kubaka.

Kuvura ibintu bya Pan-alkaline:
Umukozi wa Eflorescence yo gusukura ku isoko arashobora gukoreshwa. Uyu mukozi wogusukura ni ibara ritagira ibara rikozwe muri stioctic surfactants hamwe nibisubizo. Ifite ingaruka runaka ku isuku yubunini bwamabuye. Ariko mbere yo gukoresha, menya neza gukora icyitegererezo gito cyo kwipimisha kugirango ugerageze ngaruka hanyuma uhitemo niba uyikoresha.
