02. Resin ntụ ntụ
Ọtụtụ n'ime "resin" rọba ntụ ntụ n'ahịa nwere ihe kemịkal DBP.Ị nwere ike ịlele mmebi nke ihe kemịkal a, nke na-emetụta ọrụ nwoke na nwanyị.A na-akwakọba ọnụ ọgụgụ buru ibu nke ụdị ntụ ntụ rọba n'ụlọ nkwakọba ihe na ụlọ nyocha, ọ nwekwara mgbanwe ụfọdụ.Ahịa Beijing, nke a ma ama maka ịba ụba nke "rọba ntụ ntụ", ugbu a nwere aha dị iche iche nke "roba ntụ ntụ" nke a na-etinye n'ime ihe mgbaze: nnukwu mmiri na-eguzogide mmiri na-eguzogide mmiri, resin roba ntụ ntụ, wdg. àgwà ndị a na-ahụkarị:
1. Ogbenye dispersibility, ụfọdụ na-eche mmiri, ụfọdụ na-eche flocculent (ọ kwesịrị ịbụ a porous ihe dị ka sepiolite) na ụfọdụ ndị na-acha ọcha na ubé akọrọ ma ka na-esi ísì ọjọọ;
2. Ọ na-esi ísì nke ukwuu;
3. Agbanyela ụfọdụ agba, na agba ndị na-apụta ugbu a bụ ọcha, odo, isi awọ, nwa, ọbara ọbara, wdg;
4. Ọnụ ego nke mgbakwunye dị ntakịrị, na ọnụ ọgụgụ nke mgbakwunye maka otu ton bụ 5-12 n'arọ;
5. Ike mmalite dị mma n'anya.Simenti enweghị ike n'ime ụbọchị atọ, na mkpuchi mkpuchi nwere ike imebi ma rapara;
6. A na-ekwu na bọọdụ XPS adịghị mkpa onye ọrụ interface;
Site samples enwetara ugbu a, ọ nwere ike kwubiri na ọ bụ ihe mgbaze dabeere resin adsorbed site ìhè porous ihe, ma soplaya chọrọ ụma zere okwu ahụ bụ "ihe mgbaze", ya mere a na-akpọ ya "roba ntụ ntụ".
adịghị ike:
1. Mgbochi ihu igwe nke ihe mgbaze bụ nnukwu nsogbu.Na anyanwụ, ọ ga-ekupụ n'oge dị mkpirikpi.Ọbụna ma ọ bụrụ na ọ bụghị na anyanwụ, njikọ njikọ ga-agbaze ngwa ngwa n'ihi oghere oghere;
2. Nguzogide ịka nká, ihe mgbaze anaghị eguzogide okpomọkụ, onye ọ bụla maara nke a;
3. Ebe ọ bụ na usoro njikọ ahụ bụ ịgbari interface nke mkpuchi mkpuchi, n'ụzọ megidere nke ahụ, ọ na-ebibikwa njikọ njikọ.Ọ bụrụ na enwere nsogbu na nsogbu a na ọkwa ikpeazụ, mmetụta ahụ ga-egbu;
4. Enweghị usoro ntinye akwụkwọ na mba ọzọ.Site na ahụmịhe kemịkalụ tozuru oke na mba ofesi, ọ gaghị ekwe omume ịghara ịchọpụta ihe a.
ntụ ntụ latex enwere ike agbasa
1. Ngwaahịa latex na-agbanwe agbanwe bụ ntụ ntụ na-edozi mmiri, nke bụ copolymer nke ethylene na vinyl acetate, na mmanya polyvinyl dị ka colloid nchebe.
2. VAE redispersible latex ntụ ntụ nwere ihe nkiri na-emepụta ihe, 50% ngwọta aqueous na-emepụta emulsion, na-emepụta ihe nkiri plastik mgbe etinyere ya na iko maka awa 24.
3. Ihe nkiri a kpụrụ akpụ nwere ụfọdụ mgbanwe na mgbochi mmiri.Ọ nwere ike iru ọkọlọtọ mba.
4. Redispersible latex ntụ ntụ nwere nnukwu arụmọrụ: ọ nwere ikike njikọta dị elu, arụmọrụ pụrụ iche na arụmọrụ mmiri na-enweghị atụ, ike njikọta dị mma, na-enye ngwa agha na nguzogide alkali dị mma, ma nwee ike melite adhesion na ike ike nke ngwa agha Na mgbakwunye na plasticity, na-eyi nguzogide. na ihe owuwu, ọ nwere ngbanwe siri ike na ngwa agha mgbochi mgbawa.
resin ntụ ntụ
1. Resin roba ntụ ntụ bụ ụdị mgbanwe ọhụrụ maka ngwaahịa ndị dị ka roba, resin, polymer molecular dị elu, na ntụ ntụ rọba nke ọma;
2. Resin roba ntụ ntụ nwere n'ozuzu anwụ ngwa ngwa, na-eyi na-eguzogide, ogbenye mgbasa, ụfọdụ na-eche flocculent (ọ kwesịrị a porous ihe dị ka sepiolite), na e nwere na-acha ọcha powders (ma nwere pungent isi yiri kerosene);
3. Ụfọdụ resin powders na-emebi emebi na osisi, na mkpuchi mmiri adịghị mma.
4. Mgbochi ihu igwe na nguzogide mmiri nke resin roba ntụ ntụ dị ala karịa nke latex ntụ ntụ.Iguzogide ihu igwe bụ nnukwu nsogbu.Na anyanwụ, ọ ga-ekupụ n'oge dị mkpirikpi.Ọbụna ma ọ bụrụ na ọ bụghị na anyanwụ, njikọ njikọ ga-N'ihi oghere-ewu, ọ ga-decompose ngwa ngwa;
5. Resin roba ntụ ntụ enweghị moldability, hapụ naanị mgbanwe.Dị ka ụkpụrụ ule maka mkpuchi mkpuchi mgbidi dị n'èzí, ọ bụ naanị ọnụ ọgụgụ mmebi nke osisi polystyrene na-ezute ọkọlọtọ.Ngosipụta ndị ọzọ erughị ọkọlọtọ;
6. Resin roba ntụ ntụ nwere ike iji jikọta mbadamba polystyrene, ọ bụghị ihe mkpuchi vitrified na mbadamba ọkụ.
