Cellulose ethers bụ klaasị nke nnukwu molekụla dị arọ mmiri-soluble polymers ewepụtara na cellulose. A na-eji ha eme ihe n'ọtụtụ ebe na ụlọ ọrụ ihe owuwu dị ka ihe na-eme ka arụmọrụ na-arụ ọrụ maka ciment dabeere na ngwaahịa gypsum. N'ime ha, hydroxypropyl methylcellulose (HPMC) bụ otu n'ime ethers cellulose kachasị mkpa maka putty.
Dịka ọkachamara ọkachamara HPMC, anyị ga-akọwara gị ọrụ cellulose ether na putty. Anyị na-atụ anya na post a na-enye ụfọdụ nghọta bara uru maka ndị nwere mmasị na isiokwu a.
1. Njide mmiri
Otu n'ime isi ọrụ nke cellulose ether maka putty bụ njigide mmiri. Putty bụ ihe dị ka tapawa nke a na-eji emeju oghere na mgbawa n'elu elu dịka mgbidi, elu ụlọ na ala. Mmiri bụ ihe dị mkpa na nhazi nke putty n'ihi na ọ na-enyere aka igbari ihe ndị na-emepụta ihe ma na-enye ọrụ. Otú ọ dị, oke mmiri nwere ike ime ka putty kpoo ọkụ ma daa ngwa ngwa, na-eduga na mgbawa na njedebe dị ala.
Cellulose ether, karịsịa HPMC, na-emepụta ihe dị ka gel mgbe ejikọtara ya na mmiri, nke nwere ike ime ka njigide mmiri nke putty dịkwuo mma. Otu hydrophilic nke HPMC nwere ike ịmịkọrọ ụmụ irighiri mmiri ma gbochie ha ịpụpụ ngwa ngwa. Njirimara a na-enye ohere ogologo oge na-arụ ọrụ yana udidi putty na-agbanwe agbanwe.
2. Melite ịrụ ọrụ
Ọrụ ọzọ dị mkpa nke cellulose ether maka putty bụ imeziwanye ọrụ ya. Ịrụ ọrụ na-ezo aka na ịdị mfe nke etinyere putty na ịkpụzi iji nweta elu dị larịị. Cellulose ether nwere ike ịkwalite mmụba na mgbasawanye nke putty site n'ibelata esemokwu n'etiti ụmụ irighiri ihe na ịbawanye mmanye nke usoro ahụ.
Mgbakwunye nke cellulose ethers na putties na-ebelatakwa ikuku ikuku na-akpata site na ịgwakọta, nke nwere ike iduga n'elu ala na-adịghị mma na nkwụsị na-adịghị mma. Ojiji nke cellulose ethers na-eme ka ire ụtọ na nkwụsi ike nke putty na-eme ka ọ dịkwuo mma n'ozuzu ya na njedebe mara mma.
3. Mụbaa adhesion
Uru ọzọ nke cellulose ether maka putty bụ ụbara adhesion. A na-eji putties jupụta oghere na mgbawa, yana ịmepụta ebe dị mma maka agba ma ọ bụ ihe ndị ọzọ. Ya mere, putty ga-enwe ike ịrapara na mkpụrụ osisi ahụ ma nye njikọ siri ike.
Cellulose ether, karịsịa HPMC, nwere ike imeziwanye adhesion nke putty site n'ịme ihe nkiri n'elu nke mkpụrụ. Ihe nkiri ahụ na-eme ka kọntaktị dị n'etiti putty na mkpụrụ ahụ ma na-enyere aka mejupụta ihe na-adịghị mma n'elu. Nke a na-ebute njikọ siri ike na njedebe na-adịgide adịgide.
4. Belata mbelata
Mbelata bụ nsogbu a na-ahụkarị na putty, n'ihi na ọ nwere ike ibute mgbawa na njedebe dị ala. Cellulose ethers nwere ike inye aka belata nkwụsị nke putty site na imezi njide mmiri na ịrụ ọrụ nke putty. Mmiri na-eji nwayọọ nwayọọ na-ekpochapụ, na-enye putty ka ọ dị nro nke na-enyere aka igbochi mgbawa na mgbawa ịpụta n'oge ihicha.
Tụkwasị na nke ahụ, cellulose ether nwekwara ike ibelata nkwụsị plastik nke putty, ya bụ, nkwụsị nke na-eme n'oge ntọala mbụ. Ihe onwunwe a dị mkpa karịsịa maka ntinye ngwa ngwa ngwa ngwa, n'ihi na ọ na-enyere aka ịnọgide na-eguzosi ike n'ezi ihe nke elu ma na-egbochi ịmepụta cracks.
5. Ọganihu ka mma
N'ikpeazụ, cellulose ethers nwere ike imeziwanye ịdịte aka nke putty site n'ịkwalite nguzogide ya na ihe gburugburu ebe obibi dị ka mgbanwe okpomọkụ, iru mmiri na abrasion. Ihe na-emepụta ihe nkiri nke cellulose ether nwere ike inye ihe mgbochi nchebe n'elu putty iji gbochie ntinye mmiri na ihe ndị ọzọ na-emerụ emerụ.
Ọzọkwa, ether cellulose nwekwara ike imeziwanye ike na-agbanwe agbanwe na nguzogide mmetụta nke putty, na-eme ka ọ bụrụ ihe na-eguzogide ọgwụ na mgbawa. Ngwongwo a dị mkpa karịsịa maka ngwa ebe a na-edozi ma ọ bụ na-emetụta putties ugboro ugboro, dị ka ọrụ nrụzi ma ọ bụ ihe ịchọ mma.
na ngwụcha
Na mmechi, cellulose ethers, karịsịa HPMC, dị mkpa putty arụmọrụ na-akwalite admixtures. Ọrụ ha na-agụnye njide mmiri, nhazi nhazi nke ọma, ụbara adhesion, mbelata mbelata na nkwalite ịdịte aka. Iji cellulose ethers na-enyere aka melite ogo na arụmọrụ nke putty n'ozuzu ya, na-eme ka njedebe dị mma na ogologo ndụ. Dị ka ọkachamara HPMC emeputa, anyị na-agba mbọ inye ndị ahịa na elu-edu cellulose ether na oru nkwado.
