Polyurea irwanya ruswa itwikiriye imiyoboro n'ibigega by'imyanda
Ibisobanuro ku bicuruzwa
Ibibyimba bya polyurea bigizwe ahanini nibice bya isocyanate na amine polyether. Ibikoresho fatizo bigezweho bya polyurea bigizwe ahanini na MDI, polyole polyole, polyamine polyamine, umugozi wa amine, inyongeramusaruro zinyuranye zikora, pigment nuwuzuza, hamwe nudukoryo dukora. Ipitingi ya polyureya ifite ibiranga umuvuduko ukiza byihuse, umuvuduko wubwubatsi bwihuse, uburyo bwiza bwo kurwanya ruswa no gukora amazi, ubushyuhe bwagutse, hamwe nuburyo bworoshye. Birakwiriye cyane cyane mubigo bitandukanye byinganda nubucukuzi bwamabuye y'agaciro, parikingi, ibibuga by'imikino, nibindi, kubitaka hasi bisabwa kurwanya anti-kunyerera, kurwanya ruswa no kurwanya imyenda.
IBIKURIKIRA
- Kurwanya kwambara birenze, kwihanganira, kuramba kuramba;
- Ifite ubukana bwiza kuruta epoxy hasi, nta gukuramo cyangwa guturika:
- Coefficient yo hejuru yubuso ni ndende, bigatuma irwanya kunyerera kuruta epoxy hasi.
- Gukora firime imwe, gukama vuba, kubaka byoroshye kandi byihuse:
- Kongera gutwikira bifite adhesion nziza kandi byoroshye gusana.
- Amabara arashobora guhitamo kubuntu. Nibyiza kandi byiza. Ntabwo ari uburozi kandi bwangiza ibidukikije.
Umwanya wo kurwanya ruswa niho tekinoroji ya polyurea yinjiye hakiri kare kandi yakoreshejwe cyane mubuhanga. Mubikorwa byayo harimo kurwanya ruswa yububiko bwibyuma nkumuyoboro, ibigega byo kubikamo, ibyuma, ibirundo byibyuma, hamwe n’ibigega byo kubika imiti. Ipfunyika ry'ibikoresho ni ryinshi, ridafite ikizinga, rifite imbaraga zo kurwanya ruswa no kwangirika, rishobora guhangana n’isuri ryinshi ry’imiti y’imiti, kandi rishobora gukoreshwa igihe kirekire ahantu hashobora kuba harangiritse cyane nko mu bishanga, ibidendezi, amavuta y’umunyu, n’ahantu h'urutare nta poro, guturika, cyangwa gukuramo. Ifite ikirere cyiza. Ipitingi ya Delsil polyurea irwanya ruswa ntishobora kuvunika kabone niyo haba hari ihinduka ryimiterere yicyuma, kandi irashobora gupfuka hejuru yumurimo wose ndetse no mubihe bidasanzwe nko gusohoka cyangwa kwiheba kwimiyoboro.
Uburyo bwo kubaka
Ubuhanga bushya bwo kurwanya ruswa kubidendezi
Mugihe ibintu byo kurengera ibidukikije bigenda bikomera, amazi y’inganda, amazi y’ubuvuzi, hamwe n’ifumbire mvaruganda yo mu cyaro byose bifata uburyo bwo gukusanya hamwe. Kurwanya ruswa y'ibidendezi bya beto cyangwa agasanduku k'ibyuma birimo imyanda cyangwa amazi mabi byabaye ikintu cyambere. Bitabaye ibyo, bizatera imyanda ya kabiri kumeneka, bikaviramo kwanduza bidasubirwaho ubutaka. Dukurikije imibare ituzuye, ubuzima bwa serivisi bw’ibidendezi birwanya ruswa bikubye inshuro 15 ubw'ibidendezi bitarwanya ruswa. Ikigaragara ni uko kurwanya ruswa y’ibidendezi bitagira uruhare runini mu kubungabunga ibidukikije ahubwo ni inyungu ihishe ku mishinga.
- 1. Nyuma yo gusya neza, gukusanya ivumbi.
- 2. Igishishwa kitagira umusemburo wa primer: Igomba gukoreshwa hejuru yubutaka mbere yo kubaka. Irashobora gufunga imyenge ya capillary yubuso hasi, kugabanya inenge zo gutwika nyuma yo gutera, kandi ikongerera gufatana hagati yigitereko na sima nubutaka bwa beto. Tegereza kugeza bikize neza mbere yo gukomeza intambwe ikurikira yo kubaka.
- 3. Polyurea putty layer yo gusana (yatoranijwe hashingiwe kumiterere yimyambarire): Koresha polyurea yabugenewe yo gusana no kuringaniza. Nyuma yo gukira, koresha uruziga rusya rwamashanyarazi kugirango rusya neza hanyuma usukure vacuum.
- 4. Funga ubuso bwibanze kandi wongere gufatira hamwe. Reka bikire amasaha 12-24 (ukurikije uko hasi, hamwe nihame ryo gufunga hasi).
- 5. Shira polyurea irwanya ruswa; Nyuma yo gutsinda spray yikizamini, banza utere umwobo uhuza, hanyuma utere hejuru yimbere yumuyoboro, imiyoboro igororotse cyangwa inkokora byatewe mu ruganda, kandi ingingo zitewe kurubuga. Shira kumurongo hejuru kugeza hasi, hanyuma hepfo, hanyuma wimuke mumwanya muto muburyo bwambukiranya. Ubunini bwa coating ni 1.5-2.0mm. Uzuza gutera inshuro imwe. Uburyo bwihariye murashobora kubusanga muri "Polyurea Engineering Coating Specifications".
- 6. Kuzunguruka no gutera ikote hejuru ya polyurea: Kuvanga umukozi wingenzi hamwe nu muti wogukiza mukigereranyo cyagenwe, koga neza, hanyuma ukoreshe uruziga rwabugenewe kugirango imashini izunguruka cyangwa itera imashini kugirango utere umwenda wo hejuru wa polyurea hejuru yumuti wuzuye wa polyurea. Irinde imirasire ya ultraviolet, irinde gusaza, no guhindura amabara.
Gukumira ruswa
Mu myaka ya vuba aha, habaye iterambere ryibikoresho byo gukumira ruswa. Kuva muburyo bwambere bwo gukumira amakara yamakara kugeza kuri 3PE sisitemu yo gukumira ruswa, none kugeza kubikoresho bya polymer, ibikoresho byateye imbere kuburyo bugaragara. Kugeza ubu, uburyo bwinshi bwo kwirinda ruswa bufite ibiranga nkibibazo byo kubaka cyane, igihe gito cyo kubaho, kubungabunga bigoye mugihe cyanyuma, ndetse no kutangiza ibidukikije. Kugaragara kwa polyurea byujuje iki cyuho mumurima.
- 1. Umusenyi wo gukuraho ingese: Ubwa mbere, imiyoboro irashishwa umusenyi kugirango ikureho ingese kurwego rwa Sa2.5. Igikorwa cyo kumusenyi kigomba kurangira mumasaha 6. Hanyuma, polyurethane primer coating irakoreshwa.
- 2. Gusaba primer: Nyuma yumusenyi, progaramu idasanzwe ya solvent idafite. Nyuma ya primer yumye kugeza aho nta mazi agaragara aguma hejuru, igipfundikizo cya polyurethane. Wemeze no gusaba kwemeza guhuza polyurethane na substrate ya pipe.
- 3. Gutera polyurethane: Koresha imashini itera polyurethane kugirango utere polyurethane neza kugeza igihe uburebure bwa firime bugerweho. Ubuso bugomba kuba bworoshye, nta kwiruka, pinholes, ibibyimba, cyangwa guturika. Kubyangiritse byaho cyangwa pinholes, intoki za polyurethane zishobora gukoreshwa mugutera.
