Cellulose eriri na-ewu

Mkpa ihe owuwu eriri bụ: cellulose ether, methyl cellulose (MC), hydroxypropyl methyl cellulose (HPMC), hydroxyethyl cellulose (HEC), carboxymethyl cellulose (CMC), lignin eriri , Cellulose eriri.

N'ihi njirimara nke cellulose n'onwe ya, dị ka hydrophilicity eke, ezigbo gripping ike, nnukwu eriri kpọmkwem n'elu ebe, na elu siri ike na ike, wdg, mgbe agbakwunyere na ihe, n'okpuru omume nke mmiri na-emikpu na mpụga ike, ọ na-etolite. Ọnụ ọgụgụ dị ukwuu nke evenly ekesa ezi emep uta eri nwere ike n'ụzọ dị irè igbochi omume nke cracks kpatara plastic shrinkage, akọrọ shrinkage na okpomọkụ mgbanwe nke ihe, na budata mma n'ibu Njirimara nke ihe.

Eriri cellulose na-eme ka simenti hydrate zuru oke, na-ebelata ohere dị n'ime ihe ahụ, ma na-eme ka ihe ndị ahụ dị ntakịrị, si otú ahụ na-eme ka ntu oyi na-eguzogide mmiri, mmiri na-esi na mmiri, na ion chloride permeability nke ihe ahụ na-eme ka ihe ahụ dịkwuo mma.

(1) Mgbochi mgbawa mmetụta na ihe

A na-ekesa eriri cellulose n'ụzọ atọ n'ime ihe, nke nwere ike ibelata nrụgide nrụgide n'ọnụ ọnụ nke micro-cracks, na-ebelata ma ọ bụ wepụ ihe mgbagwoju anya nke na-akpata site na nkwụsị nke ihe ma ọ bụ ngwa agha, ma gbochie ihe omume na mgbasawanye nke micro-cracks.

(2) Melite impermeability nke ihe

The edo nkesa nke cellulose emep uta eri na ihe Nleta a na-akwado usoro, nke na-egbochi elu mmiri nkewa na mmezi nke aggregates, ebelata ọbara ọgbụgba nke ihe, ebelata ọbara ọgbụgba ọwa nke ihe, na ukwuu ebelata porosity na ihe, otú The impermeability nke. ihe a na-emeziwanye nke ọma.

(3) Melite nguzogide ntu oyi nke kọnkịtị

N'ihi ọnụnọ nke cellulose emep uta eri na ihe, ọ nwere ike n'ụzọ dị irè ibelata ịta nke tensile nchegbu na ihe kpatara otutu ifriizi-thaw cycles, na-egbochi n'ihu mgbasa nke micro-cracks. Na mgbakwunye, n'ihi nkwalite nke enweghị ike ime ihe, ọ dịkwa uru iji melite nguzogide oyi-ịza oyi.

Eriri cellulose na-enyere aka ịmịkọrọ ọrụ nke ihe ndị na-emepụta ihe mgbe ha na-emetụta ya, na n'ihi nkwụsị nke mgbawa nke eriri, mgbe a na-etinye ihe ndị ahụ na-emetụta ibu, eriri ahụ nwere ike igbochi mgbasawanye ngwa ngwa nke mgbagwoju anya, ya mere ọ nwere ike ịkwalite nke ọma. mmetụta nkwụsị nke ihe na ike siri ike.

(5) Mmelite nke ihe ogologo oge

N'ihi ezi mgbape eguzogide mmetụta nke cellulose emep uta eri, omume na mmepe nke cracks na-ukwuu belata, na Mbelata esịtidem porosity slows ala corrosion na penetration nke mmiri na mpụga gburugburu ebe obibi na chemical media, chloride salts, wdg, n'ihi. ka ọnụ ọgụgụ buru ibu nke cracks belatara, mmebi nke isi nkwado nke ihe owuwu ahụ na-ebelata, nke mere na ogologo oge nke ihe na-eme ka ọ dịkwuo mma ma na-abawanye.

(6) Mmelite nke elu okpomọkụ iguzogide ihe

N'ime ihe, karịsịa na ihe siri ike dị elu, a na-agbakwụnye eriri cellulose, n'ihi na ọ nwere ọnụ ọgụgụ dị ukwuu nke eriri monofilaments na-ekesa nke ọma, nke na-enye nkesa nke atọ na-enweghị usoro na-emepụta usoro netwọk atọ. Mgbe okpomọkụ dị n'ime nke onye na-ere ọkụ na-ekpo ọkụ na-ebili ruo 165 Mgbe okpomọkụ dị n'elu ℃, eriri ndị ahụ na-agbaze ma na-etolite ọwa njikọ njikọ maka uzuoku siri ike iji gbanarị n'ime ime ihe ahụ, n'ihi ya, ọ nwere ike izere ịgbawa nke ọma. na ọkụ na gburugburu ebe obibi na budata melite anwụ ngwa ngwa nke ihe.

The mgbochi seepage na mgbochi mgbawa eriri nwere ike welie ike na mgbochi seepage arụmọrụ nke ihe. Nchikota nke teknụzụ fiber na teknụzụ kọmpụta nwere ike ịmepụta eriri ígwè na eriri sịntetik nke nwere ike imeziwanye arụmọrụ nke ihe na imeziwanye ogo injinia obodo. Nke mbụ bụ adabara dams, ọdụ ụgbọ elu, elu-ọsọ Highway na ndị ọzọ oru ngo nwere ike igwu mgbochi cracking, mgbochi seepage, mmetụta eguzogide na flexural Njirimara, nke ikpeazụ nwere ike igbochi mmalite cracking nke ihe, na-echebe elu na mmalite ogbo nke. ihe n'ichepụta ihe. Ọ nwere mmetụta dị mma n'ịgbochi mkpuchi mkpuchi, meziwanye njide mmiri, meziwanye nkwụsi ike mmepụta na nrụpụta ihe owuwu, na-abawanye ike, na-eme ka adhesion na elu.
