Njira yosavuta yoyesera yazinthu za hydroxypropyl cellulose ether

1. Ma cellulose ethers (MC, HPMC, HEC)

MC, HPMC, ndi HEC amagwiritsidwa ntchito kwambiri pomanga putty, utoto, matope ndi zinthu zina, makamaka posungira madzi ndi kuthira mafuta. ndi zabwino.

Njira yowunikira ndi kuzindikira:

Yesani 3 magalamu a MC kapena HPMC kapena HEC, ikani mu 300 ml ya madzi ndikugwedeza mpaka itasungunuka kwathunthu mu njira yothetsera, ikani yankho lamadzi mu botolo lamadzi, loyera, lopanda kanthu, kuphimba ndi kulimbitsa kapu, ndi sungani kusintha kwa guluu m'malo a -38°C. Ngati yankho lamadzimadzi liri lomveka bwino komanso lowonekera, lokhala ndi kukhuthala kwakukulu komanso madzi abwino, zikutanthauza kuti mankhwalawa ali ndi maonekedwe abwino oyambirira. Pitirizani kuyang'ana kwa miyezi yoposa 12, ndipo imakhalabe yosasinthika, kusonyeza kuti mankhwalawa ali okhazikika bwino ndipo angagwiritsidwe ntchito molimba mtima; ngati njira yamadzimadzi imapezeka kuti imasintha pang'onopang'ono mtundu, kukhala wochepa thupi, kukhala turbid, kukhala ndi fungo la rancid, kukhala ndi matope, kukulitsa botolo, ndi kuchepetsa botolo thupi Kusinthika kumasonyeza kuti khalidwe la mankhwala si labwino. Ngati atagwiritsidwa ntchito popanga zinthu, zimabweretsa kusakhazikika kwazinthu.

2. CMCI, CMCS

Kukhuthala kwa CMCI ndi CMCS kuli pakati pa 4 ndi 8000, ndipo amagwiritsidwa ntchito makamaka pakuyika khoma ndi zida zopaka pulasitala monga wamba wamkati wamkati wamkati ndi pulasitala posungira madzi ndi kuthira mafuta.

Njira yowunikira ndi kuzindikira:

Yesani 3 magalamu a CMCI kapena CMCS, ikani mu 300 ml ya madzi ndikugwedeza mpaka itasungunuka kwathunthu, ikani yankho lake lamadzi mu botolo lamadzi, loyera, lopanda kanthu, kuphimba ndi kulimbitsa kapu, ndikuyiyika. mu Onani kusintha kwa njira yake yamadzimadzi m'malo a ℃, ngati njira yamadzimadzi ikuwonekera, yokhuthala, komanso yamadzimadzi, zikutanthauza kuti mankhwalawa amamva bwino pachiyambi, ngati njira yamadzimadzi ndi turbid ndipo ali ndi matope, zikutanthauza kuti mankhwala ali ore ufa, ndipo mankhwala aipitsidwa. . Pitirizani kuyang'ana kwa miyezi yoposa 6, ndipo ikhoza kukhalabe yosasinthika, kusonyeza kuti mankhwalawa ali ndi kukhazikika bwino ndipo angagwiritsidwe ntchito molimba mtima; ngati sichingasungidwe, zikuwoneka kuti mtunduwo udzasintha pang'onopang'ono, yankho lidzakhala lochepa thupi, lidzakhala lamtambo, padzakhala matope, fungo la rancid, ndipo botolo lidzatupa, kusonyeza kuti mankhwalawa ndi osakhazikika, ngati agwiritsidwa ntchito mu mankhwala, izo zimabweretsa mavuto khalidwe mankhwala
