Mu myaka ya vuba aha, ifu nyinshi ya resin rubber, ifu ikomeye cyane idapfa amazi n'indi fu ihendutse cyane ya rubber yagaragaye ku isoko kugira ngo isimbuze emulsion gakondo ya VAE (vinyl acetate-ethylene copolymer), yumishwa ikanakorwa mu ifu ya rubber ishobora kongera gukoreshwa. Ifu ya latex itatanye, none se itandukaniro riri hagati y'ifu ya resin n'ifu ya latex ishobora kongera gukoreshwa, ese ifu ya resin ishobora gusimbura ifu ya latex ishobora kongera gukoreshwa?
Sesengura muri make itandukaniro riri hagati y’ibyo byombi kugira ngo urebe uko byagenda:
01. Ifu ya latex ishobora kongera gushonga
Kugeza ubu, ifu ya latex ishobora gusubirwamo ikoreshwa cyane ku isi ni: ifu ya acetate ya vinyl na ethylene copolymer (VAC / E), ethylene, vinyl chloride na vinyl laurate ternary copolymer powder (E / VC / VL), aside acetic ester ya vinyl, ethylene na aside iri hejuru ya vinyl ester ternary copolymer powder (VAC / E / VeoVa), izi fu eshatu za latex zishobora gusubirwamo ziganje ku isoko ryose, cyane cyane vinyl acetate na ethylene copolymer powder VAC / EE, zifite umwanya wa mbere mu rwego rw'isi kandi zigaragaza imiterere ya tekiniki ya polima ishobora gusubirwamo. Ni igisubizo cyiza cya tekiniki mu bijyanye n'uburambe mu tekiniki ku bijyanye na polima zikoreshwa mu guhindura morti:
1. Ni imwe muri polimeri zikoreshwa cyane ku isi;
2. Ubunararibonye mu bijyanye no gushyira mu bikorwa imirimo y'ubwubatsi ni bwo buruta ubundi bwose;
3. Ishobora kuzuza imiterere ya rheological isabwa na mortical (ni ukuvuga ubushobozi bwo kubaka bukenewe);
4. Resine ya polymer iri kumwe n'izindi monomer ifite imiterere ya VOC (ibintu bihindagurika mu buryo bw'umwimerere) n'umwuka ushyuha cyane;
5. Ifite imiterere yo kudahangarwa neza n'imiraba ya UV, kudahangarwa neza n'ubushyuhe kandi igakomeza igihe kirekire;
6. Ubudahangarwa bukomeye ku gushonga kw'amazi;
7. Ifite ubushyuhe bwinshi bw'impinduka mu kirahuri (Tg);
8. Ifite ubushobozi bwo guhuza neza, koroherana no gukora ibintu mu buryo bwiza;
9. Kuba afite uburambe burambye mu gukora imiti ikoreshwa mu buryo bwo gukora ibicuruzwa bifite ireme rihamye n'uburambe mu kubungabunga uburyo bibikwa;
10. Biroroshye cyane kubivanga na koloyide irinda (polyvinyl alcohol) kandi ifite ubushobozi bwo gukora neza.
02. Ifu y'ibinure
Ifu nyinshi ya "resin" ya rubber iri ku isoko irimo ikintu cyitwa DBP. Ushobora kugenzura ingaruka z'iki kintu, bigira ingaruka ku mibonano mpuzabitsina y'abagabo. Ifu nyinshi y'ubu bwoko bw'ifu ya rubber irundanyirijwe mu bubiko no muri laboratwari, kandi ifite impinduka runaka. Isoko rya Beijing, rizwiho ubwinshi bwa "ifu ya rubber", ubu rifite amazina atandukanye ya "ifu ya rubber" ivanze mu bintu bishongesha: ifu ya rubber ikomeye cyane idapfa amazi, ifu ya resin, nibindi. Ibiranga bisanzwe:
1. Kutanyagurika nabi, bimwe bikumva bitose, ibindi bikumva bitose (bigomba kuba bifite imyenge nka sepiolite) kandi bimwe ni umweru kandi byumye gato ariko biracyafite impumuro mbi;
2. Inuka cyane;
3. Hari amabara amwe yongewemo, kandi amabara agaragara ubu ni umweru, umuhondo, imvi, umukara, umutuku, n'ibindi;
4. Ingano y'inyongera ni nto cyane, kandi ingano y'inyongera kuri toni imwe ni 5-12 kg;
5. Ingufu za mbere ziba nziza cyane. Sima nta mbaraga igira mu minsi itatu, kandi ikibaho cyo gukingira gishobora kwangirika no gufatwa;
6. Bivugwa ko XPS board idakeneye agent yo gukoresha interineti;
Binyuze mu ngero zabonetse kugeza ubu, byafatwa nk'aho ari resin ishingiye ku binyabutabire yinjizwa n'ibikoresho bifite imyenge yoroheje, ariko umucuruzi arashaka kwirinda nkana ijambo "ibinyabutabire", bityo byitwa "ifu y'umukara".
inzitizi:
1. Ubudahangarwa bw'ikirere bw'umusemburo ni ikibazo gikomeye. Mu zuba, uzashira mu gihe gito. Nubwo waba utari ku zuba, aho uhurira n'umusemburo hazashira vuba bitewe n'imiterere y'aho uboshye;
2. Kurwanya gusaza, imiti isukura ntirwanya ubushyuhe, buri wese arabizi;
3. Kubera ko uburyo bwo guhuza ari ugusesa umurongo w’ikibaho cyo gukingira, ahubwo byanangiza umurongo w’imikoranire. Iyo habayeho ikibazo kuri iki kibazo mu gihe cya nyuma, ingaruka zizahitana;
4. Nta rugero na rumwe rwo gukoreshwa mu bihugu by'amahanga. Kubera uburambe bw'ibanze bw'imiti mu mahanga, ntibishoboka kutayibona.
Ifu ya latex ishobora kongera gushonga
1. Ifu ya latex ishobora gukurwamo ni ifu ishobora gukurwamo amazi, ikaba ari copolymer ya ethylene na vinyl acetate, hamwe na polyvinyl alcohol nk'irinda.
2. Ifu ya latex ishobora gukurwamo ya VAE ifite ubushobozi bwo gukora firime, 50% by'umuti w'amazi ukora emulsion, kandi ikora firime isa na pulasitiki nyuma yo gushyirwa ku kirahure mu gihe cy'amasaha 24.
3. Firime yakozwe ifite ubushobozi bwo koroshya ibintu no kwirinda amazi. Ishobora kugera ku rwego rw'igihugu.
4. Ifu ya latex ishobora guhindurwa ifite ubushobozi bwo hejuru: ifite ubushobozi bwo gufatanya cyane, imikorere yihariye n'imikorere idasanzwe yo kudapfa amazi, imbaraga nziza zo gufatanya, ikomeza ubudahangarwa bwiza bwa alkali, kandi ishobora kunoza uburyo ifatana n'imbaraga zo gupfunyika kwa mortiweri Uretse kuba ifite plastike, idashira kandi ikozwe, ifite ubushobozi bwo koroha cyane muri mortiweri irwanya gucika.
ifu ya resin
1. Ifu ya resin rubber ni ubwoko bushya bw'uburyo bwo guhindura ibintu nka rubber, resin, polymer nyinshi, n'ifu ya rubber isya neza;
2. Ifu ya resin rubber irakomeye muri rusange, irakomera, ntikwirakwira neza, imwe yumva idafite imyenge (igomba kuba ifite imyenge nka sepiolite), kandi hari ifu yera (ariko ifite impumuro ikaze nk'iya peteroli);
3. Ifu zimwe na zimwe za resin zihumanya ikirere, kandi kwirinda amazi si byiza.
4. Ubudahangarwa bw'ikirere n'ubudahangarwa bw'amazi bw'ifu ya resin rubber biri hasi ugereranyije n'ifu ya latex. Ubudahangarwa bw'ikirere ni ikibazo gikomeye. Mu zuba, buzashira mu gihe gito. Nubwo butaba ku zuba, aho buhurira buzashira Kubera imiterere y'aho buherereye, buzabora vuba;
5. Ifu ya resin rubber ntishobora gushonga, ndetse no koroha. Dukurikije ibipimo ngenderwaho byo gupima sima yo hanze y’urukuta, igipimo cy’ibyangiritse bya polystyrene board ni cyo cyonyine cyujuje ubuziranenge. Ibindi bimenyetso ntabwo bihuye n’ubuziranenge;
6. Ifu ya resin rubber ishobora gukoreshwa gusa mu guhuza amabati ya polystyrene, ntabwo ari amasaro ya vitrified n'amabati adashya.
