Gutera epoxy no gusiga Halar

I. Gusiga amavuta ya epoxy ni iki?

Irangi rya epoxy spray ni irangi rigizwe n'ibice bibiri rifite epoxy resin nk'ikintu cy'ingenzi gikora filime. Rishyirwa ku buso bw'icyuma hakoreshejwe irangi cyangwa brush kugira ngo rikore urwego rurinda. Rirangwa no gufatana cyane no kurwanya cyane gushishwa kwa cathodic. Irangi rimwe rishobora kugera ku bwubatsi bunini (kugeza kuri mikoroni 1250) ritaragwa. Rivurwa ku bushyuhe bw'icyumba kandi ryoroshye kubakwa. Irangi rya epoxy rikwiriye kurinda isuri no kwangirika kw'imiyoboro, ibikoresho, ipompo na valve n'ibindi bikoresho, kandi ubushyuhe bwo gukora bushobora kugera kuri dogere selisiyusi 120.

II. Gusiga irangi rya Halar ni iki?

Halar ni izina ry'ubucuruzi rya ECTFE (ethylene-chlorotrifluoroethylene copolymer) fluoropolymer powder coating, ikaba ari ibikoresho bifite fluorine ikora neza cyane. Ishyirwa ku buso bw'icyuma binyuze mu buryo bwo gutera amashanyarazi, aho ubushyuhe bushobora gushonga hagati ya 220-245°C n'ubushyuhe ntarengwa bwo gukoreshwa bungana na 150°C.

III.Ni irihe tandukaniro riri hagati y’ibi byombi mu kurwanya ingese mu buryo bwa shimi?

Irangi rya halar rirushaho kuba ryiza kandi rirusha izindi mu kurwanya imiti. Rishobora kwihanganira aside ikomeye hafi ya zose, base zikomeye n'imiti ya oZrganic ifite pH iri hagati ya 1-14. Rishobora kwinjizwa mu bintu bidasanzwe nka aside sulfure ya 98% na aside hydrochloric ya 37% kuri 121°C mu gihe cy'iminsi 30. Impinduka z'uburemere bw'irangi ziri munsi ya 1% kandi imiterere ya mekanike nta mpinduka zigaragara igira. Rifite ubushobozi bwo kudakoresha amazi n'ubudahangarwa bwo kwinjira, bishobora gukumira neza imyuka yangiza kwinjira mu kirangi no kugera ku gice cy'icyuma. Nubwo irangi rya epoxy naryo rifite ubudahangarwa bwiza bwa shimi, ubushobozi bwaryo bwo kwihanganira aside ikomeye (nka aside sulfure, aside hydrochloric) n'ubushyuhe bwinshi ni buke cyane ugereranyije n'irangi rya halar.

IV.Ni iyihe irusha izindi mu bijyanye n'imikorere y'ubuso no kuramba kwayo?

Ubuso bw'igitambaro cya Halar buraryoshye cyane (ubushyuhe busanzwe bwa Ra ni nka 22nm gusa), ibyo bikaba ari byiza cyane kuruta igitambaro cya epoxy. Ubuso bworoshye bushobora kubuza gufatana no kwirundanya kw'uduce n'imyunyu y'icyuma, kugabanya ikorwa rya biofilm, kugabanya ibyago byo kugira utwenge tw'imashini, no kongera ubushobozi bwo kurwanya ingese. Byongeye kandi, igitambaro cya Halar kirakomeye, ntigishisha kandi ntigitera ingaruka, kandi gifite ubudahangarwa bukomeye bwa UV, bityo ntikizashira cyangwa ngo gishire iyo gikoreshejwe hanze.

V. Ni gute wahitamo umuti ukwiye wo gusiga?

Birasabwa guhitamo irangi rya Halar mugihe——

1. Guhura n'aside ikomeye, alkali ikomeye cyangwa imiti ivanze yangiza;

2. Ubushyuhe bw'akazi burenga 120℃ (ntarengwa 150℃);

3. Ahantu ho hanze cyangwa ahantu hakomeye haterwa n'imirasire ya ultraviolet;

4. Hakenewe ubuso bworoshye cyane kugira ngo utunyangingo tudafatana;

Ni byiza guhitamo irangi rya epoxy mu bihe bikurikira:

1. Ahantu hadakora neza cyangwa hadakora neza, ubushyuhe buri munsi ya 120°C;

2. Igihe cyo kubaka kirakomeye kandi gisaba gusanwa vuba;

3. Kugenzura ibiciro birakomeye cyane.

VI.Umwanzuro

Tianjin Tanggu Amazi-Ikidodo Valve Co, Ltd.ifite itsinda ry'abahanga mu bya tekiniki rishobora gukora ibintu bishyavalve z'ibinyugunyugu, valve zo mu irembo, valve zo kugenzuran'ibindi bikoresho bya valve hakurikijwe imiterere yawe yihariye y'akazi, kandi tugatanga ibisubizo byo gutera umuti byujuje ibisabwa byihariye byo kurwanya ingese. Byaba ari epoxy spraying cyangwa Halar coating, dushobora guhitamo neza ibikoresho no kubyubaka mu buryo bwa siyansi kugira ngo valve ikomeze kuba nziza kandi yizewe mu bihe bikomeye. Murakaza neza gutanga ibisabwa mu bijyanye n'imikorere yanyu, kandi tuzabakorera igisubizo cyihariye cya valve na coating.
