Ziwiri zikuluzikulu zomatira (epoxy, polyurethane)

Ziwiri zikuluzikulu zomatira - gulu la zomatira apamwamba, monga solvents zimenezo sinabweretse. The Gawo - resins (binders) ndi hardeners (kusungidwa padera, kungakhale kaya kuyimitsidwa kapena ufa).

The mankhwala anachita kuti akuyamba pambuyo kusakaniza zigawo ziwiri izi, zikuchokera mankhwala, kukhala mphindi zochepa koyamba guluu wolimba mphamvu. Akuchiritsa liwiro zimadalira kutentha ndi khalidwe la chisanadze anamuvula. mphamvu yomaliza anaimba pambuyo maola angapo.

Zomatira epoxy ziwiri zikuluzikulu bwino kukonzekera malangizo mogwirizana ndi kufanana mmenemo ndi kugwira nthawi. Pamene ogwirizana ndi magawo awiri angathe kugwiritsidwa ntchito mbali imodzi ya activator, ndi zina - ndi utomoni. Pamene polumikiza zigawo ndi analankhulana m'njira imene tafotokoza pamwambapa.

The ntchito yaikulu ya zomatira epoxy ndi zipangizo osakhala porous (onse kupatula kupanga) kuti ayenera adzatsekeredwa glued. Pakuti wamkulu utomoni mphamvu mwina chitetezo ndi fiberglass. Njira imeneyi kumatithandiza kuthetsa mavuto zovuta kuti uka, monga kukonza makina. Nthawi zina zomatira ziwiri zikuluzikulu ndi anawonjezera chiwerengero mkulu wa ufa zitsulo ndi ntchito ngati kuwotcherera ozizira. United Choncho zinthu awonjezera mphamvu.

Pakuti makamaka cholimba ndi odalirika woona ziwiri zikuluzikulu polyurethane zomatira, ntchito pafupifupi dera lililonse. Izo mwangwiro chimatsatira billets yekha zikopa, zinthu zamatabwa (kuphatikizapo katundu), zotayidwa, galasi, chitsulo, mwala achilengedwe. Izi zomatira ziwiri zikuluzikulu si mantha chinyezi, chotero oyenera kumanga zipinda ndi chinyezi mkulu (mwachitsanzo mu bafa, kusamba ndi zina zotero. D.). Ndi abwino kwa ntchito chikugwirizana ndi kuika matailosi (kuphatikizapo kukweza zithunzi ndi Zithunzi), chifukwa gluing joinery, chifukwa pamakoma mwala.

Chifukwa cha zomatira polyurethane, kuika "ofunda pansi" dongosolo osati amapulumutsa nthawi, komanso ndalama ndi mphamvu. Kaya mtundu wa pansi pogona, kale pambuyo maola eyiti, inu simungakhoze basi kuyenda pa izo, komanso kukonza mipando. zomatira izi (Osati kudalira analogi) pafupifupi zotanuka, choncho sakubwerera ndipo alibe kutambasula. makhalidwe amenewa anakhalabe ngakhale pansi pa katundu tima kwambiri.

kudalirika kuti ndi chimodzi mwa waukulu muyezo kusankha kwa mafakitale nsapato ndi shoemakers yaing'ono. Kaya dongosolo yekha (PVC, porous, ndi zina zotero. D.), Polyurethane zomatira nsapato analanda padziko kwambiri kuti kuswa iwo pambuyo kuyanika n'zosatheka. nsapato awa si mantha mvula, amapereka omasuka, wabwino ndi zosangalatsa.

Ziwiri zikuluzikulu zomatira (polyurethane, epoxy) makamaka lolimba ndiponso cholimba, m'njira analanda mwatsatanetsatane, kugwirizana m'mfundo molimba mtima m'malo Anzawo. Iwo ntchito pafupifupi mitundu yonse ya ntchito, kaya mlingo wa kwambiri. Ziwiya zadothi, matailosi, njerwa kugwira "imfa", nchifukwa chake anthu amene kale ntchito zomatira ziwiri zikuluzikulu amusankha kachiwiri.
