Njira yosavuta yoyesera zinthu za hydroxypropyl cellulose ether

1. Ma ether a cellulose (MC, HPMC, HEC)

MC, HPMC, ndi HEC nthawi zambiri amagwiritsidwa ntchito popanga ma putty, utoto, matope ndi zinthu zina, makamaka posunga madzi ndi mafuta. Ndi yabwino.

Njira yowunikira ndi kuzindikira:

Yesani magalamu atatu a MC kapena HPMC kapena HEC, ikani mu 300 ml ya madzi ndikusakaniza mpaka itasungunuka kwathunthu kukhala yankho, ikani yankho lake lamadzi mu botolo lamadzi loyera, lowonekera, lopanda kanthu, phimbani ndikulimbitsa chivundikirocho, ndikuchiyika. Onani kusintha kwa yankho la guluu pamalo ozungulira -38°C. Ngati yankho lamadzi lili loyera komanso lowonekera bwino, lokhala ndi kukhuthala kwakukulu komanso kusinthasintha kwabwino, zikutanthauza kuti chinthucho chili ndi mawonekedwe abwino poyamba. Pitirizani kuyang'ana kwa miyezi yoposa 12, koma sichinasinthebe, kusonyeza kuti chinthucho chili ndi kukhazikika bwino ndipo chingagwiritsidwe ntchito molimba mtima; ngati yankho lamadzi lipezeka kuti likusintha pang'onopang'ono mtundu, kukhala lochepa thupi, kukhala lotayirira, kukhala ndi fungo loipa, kukhala ndi matope, kukulitsa botolo, ndikuchepetsa thupi la botolo. Kusintha kumasonyeza kuti khalidwe la chinthucho silabwino. Ngati ligwiritsidwa ntchito popanga zinthu, limabweretsa kusasunthika kwa khalidwe la chinthucho.

2. CMCI, CMCS

Kukhuthala kwa CMCI ndi CMCS kuli pakati pa 4 ndi 8000, ndipo amagwiritsidwa ntchito kwambiri popanga zinthu zoyezera makoma ndi kupaka pulasitala monga putty wamba wamkati wa khoma ndi pulasitala wa plasitala kuti madzi asungidwe komanso mafuta.

Njira yowunikira ndi kuzindikira:

Yesani magalamu atatu a CMCI kapena CMCS, ikani mu 300 ml ya madzi ndikusakaniza mpaka itasungunuka kwathunthu kukhala yankho, ikani yankho lake lamadzi mu botolo lamadzi lamchere loyera, lowonekera, lopanda kanthu, phimbani ndikulimbitsa chivundikirocho, ndikuchiyika. Onani kusintha kwa yankho lake lamadzi mumlengalenga wa ℃, ngati yankho lamadzi ndi lowonekera, lokhuthala, komanso lamadzimadzi, zikutanthauza kuti chinthucho chikumva bwino pachiyambi, ngati yankho lamadzi ndi lopanda madzi ndipo lili ndi matope, zikutanthauza kuti chinthucho chili ndi ufa wa ore, ndipo chinthucho chasakanizidwa. Pitirizani kuyang'anitsitsa kwa miyezi yoposa 6, ndipo chikhoza kukhalabe chosasinthika, kusonyeza kuti chinthucho chili ndi kukhazikika bwino ndipo chingagwiritsidwe ntchito molimba mtima; ngati sichingasungidwe, zimapezeka kuti mtundu wake udzasintha pang'onopang'ono, yankholo lidzakhala lochepa, lopanda mitambo, padzakhala matope, fungo loipa, ndipo botolo lidzatupa, kusonyeza kuti chinthucho sichikhazikika, ngati chigwiritsidwa ntchito mu chinthucho, chidzayambitsa mavuto a khalidwe la chinthucho.
