Kodi pali zovuta zina za chilengedwe pakuwonjezera HPMC mumatope?

Hydroxypropyl methylcellulose (HPMC) ndi chowonjezera chomwe chimagwiritsidwa ntchito nthawi zambiri ndipo chimagwiritsidwa ntchito kwambiri mumatope, koma zomwe zingakhudze chilengedwe chakopa chidwi.

Biodegradability: HPMC ili ndi mphamvu yowononga m'nthaka ndi madzi, koma chiwopsezo chake ndi chochepa. Izi ndichifukwa choti mapangidwe a HPMC ali ndi mafupa a methylcellulose ndi unyolo wambali wa hydroxypropyl, zomwe zimapangitsa kuti HPMC ikhale yokhazikika. Komabe, pakapita nthawi, HPMC idzawonongeka pang'onopang'ono ndi tizilombo toyambitsa matenda ndi michere, ndipo pamapeto pake imasandulika kukhala zinthu zopanda poizoni ndikumwedwa ndi chilengedwe.

Kukhudza chilengedwe: Kafukufuku wina wasonyeza kuti zowononga za HPMC zitha kukhala ndi vuto linalake pazachilengedwe m'madzi. Mwachitsanzo, zinthu zowonongeka za HPMC zingakhudze kukula ndi kuberekana kwa zamoyo za m'madzi, potero zimakhudza kukhazikika kwa chilengedwe chonse cha m'madzi. Kuphatikiza apo, zinthu zowononga za HPMC zitha kukhalanso ndi vuto linalake pazantchito zazing'onoting'ono komanso kukula kwa mbewu m'nthaka.

Kasamalidwe ka chiwopsezo cha chilengedwe: Pofuna kuchepetsa kukhudzidwa kwa HPMC pa chilengedwe, njira zina zitha kuchitidwa. Mwachitsanzo, popanga ndikusankha zida za HPMC, lingalirani momwe zimawonongera ndikusankha zida zothamanga mwachangu. Konzani kugwiritsa ntchito HPMC ndikuchepetsa kuchuluka kwa zinthu zomwe zimagwiritsidwa ntchito, potero kuchepetsa kukhudzidwa kwake pa chilengedwe. Kuphatikiza apo, kafukufuku wina atha kuchitidwa kuti amvetsetse momwe HPMC imawonongera komanso momwe zinthu zimawonongera chilengedwe, kuti athe kuunika bwino ndikuwongolera kuopsa kwa chilengedwe.

Kuwunika momwe chilengedwe chikuyendera: Nthawi zina, pangakhale kofunikira kuunika momwe chilengedwe chimakhudzira zomwe zingachitike panthawi yopanga kapena kugwiritsa ntchito HPMC. Mwachitsanzo, pamene Anhui Jinshuiqiao Building Materials Co., Ltd. anachita ntchito yokonzanso ndi kukulitsa ndi linanena bungwe la 3,000 matani 3,000 wa HPMC pachaka, kunali koyenera kuchititsa chilengedwe kuwunika mogwirizana ndi "Measures for Public Participation in Environmental. Impact Assessment” ndikusindikiza zidziwitso zoyenera kuwonetsetsa kuti zomwe polojekiti ikuchita pa chilengedwe ikuyendetsedwa moyenera.

Kugwiritsa ntchito m'malo enaake: Kugwiritsa ntchito HPMC m'malo enaake kumafunikanso kuganizira momwe chilengedwe chimakhudzira. Mwachitsanzo, mu mkuwa zakhudzana nthaka-bentonite chotchinga, Kuwonjezera HPMC akhoza bwino kulipira attenuation ake odana seepage ntchito mu heavy zitsulo chilengedwe, kuchepetsa kuphatikizika kwa mkuwa zakhudzana bentonite, kukhalabe dongosolo mosalekeza bentonite. , ndi kuwonjezeka kwa chiŵerengero cha kusakaniza kwa HPMC, kuchuluka kwa kuwonongeka kwa chotchinga kumachepetsedwa ndipo ntchito yotsutsa-seepage imapangidwa bwino.

Ngakhale kuti HPMC imagwiritsidwa ntchito kwambiri pantchito yomanga, chilengedwe chake sichinganyalanyazidwe. Kafukufuku wa sayansi ndi njira zoyendetsera bwino ndizofunikira kuti awonetsetse kuti kugwiritsa ntchito HPMC sikukhala ndi zotsatirapo zoyipa pa chilengedwe.
