Ubusembwa butatu busanzwe bwa Polyurethane: Uduce duto, Uduce duto duto, n'ibimenyetso by'amazi - Impamvu nyamukuru n'ibisubizo by'ubuhanga
Impamvu izi nenge zikomeza kugaragara mu musaruro
Mu bikorwa byo gushushanya no gushushanya polyurethane,imyobo y'imigozi, imyenge y'ingufu, n'ibimenyetso by'amazi atembani zimwe mu nenge zikunze kugaragara ku buso mu buryo bworoshye no gukomera bwa polyurethane.
Nubwo nyuma yo gukosora kenshi, ibi bibazo bikunze kugaragara, bigaragaza ko impamvu nyamukuru idakunze kuba ikosa rimwe mu mikorere. Ahubwo, biterwaubusumbane mu rwego rwa sisitemubikubiyemo:
- Kugenzura ubushuhe bw'ibikoresho fatizo
- Uburyo bwo gukora ibikorwa (uburyo bwo gusohora ifuro ugereranije n'uburyo bwo gusiga ifuro)
- Gupima no kuvanga neza
- Igishushanyo mbonera cyo gushyiramo umwuka n'uburyo bwo kuzuza ifu
- Kugenzura ubushyuhe bw'imikorere
Kugira ngo umusaruro uhore uhamye, hakozwe nezasisitemu yo gukora polyurethaneni ngombwa.
Menya byinshi ku bijyanye na sisitemu nziza ku porogaramu zitandukanye:
Ibisubizo bya sisitemu ya polyurethane
1. Uduce tw'ingomero (Uduce duto, Uduce duto tw'ingomero, Uduce duto tw'ingomero)
1.1 Impamvu nyamukuru zituma habaho kongera kwisubiramo
(1) Kwanduzwa n'ubushuhe — Impamvu nyamukuru
Ubushuhe muri polyols, catalysts, silicone surfactants, cyangwa inyongeramusaruro ni byo bikunze gutera utwenge tw’ingobyi.
Inkomoko z'ingenzi zirimo:
- Gufata ibikoresho fatizo byifashishwa mu gukurura
- Ubushyuhe mu bigega byo kubikamo ibintu
- Hydrolise ya Isocyanate
- Ibikoresho bitose cyangwa ibikoresho bisohora amazi
- Ubushuhe bwinshi bw'ikirere
Amazi agirana na isocyanate (NCO) kugira ngo akore umwuka wa CO₂. Iyo uduheri tudashobora gusohoka mbere yo gukaraba,imyobo ifunze burundu mu nyubako.
Imiti irwanya ubushuhe isaba imiterere myiza y’imiti:
Inzu ya sisitemu ya polyurethane
(2) Gufata umwuka mu gihe cyo kuvanga
- Umuvuduko ukabije wo kuvanga
- Uburebure bwinshi bw'amazi mu gihe cyo gusuka
- Igishushanyo mbonera cy'imitwe ivanze ivanze
Ibi bintu bitanga utubumbe tw’umwuka duto tudashobora gusohoka mu gihe runaka.
(3) Kudahuza kw'ifuro n'ubushyuhe
- Gutemba vuba cyane → uduheri twafatiwe mu nkuta zikomeye
- Ifuro ryihuse cyane → guturika kw'ibibyimba
- Ubushobozi buke bwo gukora surfactant ya silikoni → imiterere y'uturemangingo idahamye
Guhitamo "Catalyst" bigira uruhare runini mu kuringaniza umuvuduko w'inyishu:
Katalysti za Polyurethane Amine
(4) Impumuro mbi zo guhumeka kw'ibimera
- Imiyoboro y'imyobo ifunze
- Imiterere mibi y'imiyoboro y'amazi
- Umwanya wo gufata umwuka ufunga ifu mbere y'igihe
1.2 Ibisubizo by'Ubwubatsi
- Kunoza uburyo bwo gufunga ibikoresho fatizo no kugenzura ubushuhe
- Koresha uburinzi bwa azote mu bidukikije bikonje
- Shyushya kandi wumishe ifumbire neza
- Ongera ingufu zo kuvanga no kugabanya uburyo umwuka winjiramo
- Hindura uburyo amine/tin catalyst ikoreshwa kugira ngo igire igihe gihamye cyo gukora isuzuma ry'imikorere
- Kunoza imiterere y'aho umwuka unyura no gufunga ifu
2. Umwobo wo gushonga (Ibimenyetso by'ubuso, Gusenyuka kw'inkombe, Gucika kw'inkombe)
2.1 Impamvu nyamukuru zituma habaho kongera kwisubiramo
(1) Gutakaza ubushobozi bwo gukora cyane nyuma yo kugabanuka
- Ubucucike buke bw'imiyoboro
- Igipimo cy'imisoro yo mu rwego rwo hasi (NCO)
- Igipimo cyo kwaguka kw'ifuro kinini
Bitera kwifata imbere nyuma yo gukonja no gusenyuka kw'ubuso.
(2) Gutanga ubushyuhe butangana no gukwirakwiza ubushyuhe
- Ibice binini bikira buhoro kurusha ibice bito
- Itandukaniro ry'imihangayiko mu gace runaka
- Ubucucike buhindagurika mu gice cyose
(3) Kutazuza neza cyangwa imiterere mibi y'irembo
- Umwobo wuzuyemo ibintu bidahagije
- Kugera nabi kw'amazi mu turere two ku mpera z'isi
- Aho irembo ry'inshinge rishyirwa nabi
(4) Gukuraho imburagihe
Gusenyuka vuba bituma inyubako zisenyuka bitewe no kudakora neza kw'imbere.
2.2 Ibisubizo by'Ubwubatsi
- Ongera gatoIgipimo cya NCO (urugero rwa 1.05 → 1.10)
- Ongera uburemere bw'ishoti kandi urebe neza ko rirenze urugero
- Kuringaniza ubushyuhe bw'ibihumyo n'ubushyuhe bw'ibikoresho
- Ongera igihe cyo gukaraba mbere yo kugabanya
- Kunoza uburinganire bw'imikorere hakoreshejwe uburyo bwo kunoza urwego rwa sisitemu
Ubufasha mu kunoza sisitemu:
Ibisubizo bya sisitemu ya polyurethane
3. Ibimenyetso by'Inzira (Imirongo y'Inzira, Imirongo yo Gusudira, Imirongo, Imiraba yo Ku Buso)
3.1 Impamvu nyamukuru zituma habaho kongera kwisubiramo
(1) Uruzi rw'amazi rudahindagurika
- Ihindagurika ry'umuvuduko wa pompe
- Kudahinduka kw'igipimo cyo gupima
- Urujya n'uruza rw'inshinge rutemba cyane
(2) Ubushyuhe budahuye
- Ubushyuhe buke bw'ibihumyo butera uruhu rudakora neza
- Uruvange rubi rw'imigezi
- Ihindagurika ry'ubushyuhe ritera inenge zidahuye
(3) Igishushanyo mbonera kibi cy'irembo
- Irembo rimwe rifite inzira ndende y'amazi
- Impande nyinshi zikora imirongo yo gusudira
- Gutembera kw'imodoka guterwa n'irembo rito
(4) Ibibazo byo Kudakora neza / Ibibazo by'Umukozi Urekura
- Uburyo bworoshye bwo gutembera mu buryo buciriritse
- Igipfukisho cy'ibikoresho byo kurekura kidahuje
- Kwanduza imiterere y'ubutaka bibuza kwivanga
3.2 Ibisubizo by'Ubwubatsi
- Gutuza sisitemu zo gupima no kuvoma
- Gumana ubushyuhe buhoraho bw'ibihumyo n'ubushyuhe bw'ibikoresho
- Ongeraho ingingo z'inyongera ku miyoboro miremire
- Kunoza uburyo bwo gutembera hakoreshejwe uburyo bwo guhindura imiterere y'ibicuruzwa
Kunoza imikorere y'urusobe rw'imikoreshereze ...
Ibibuza umuriro n'ibisubizo by'inyongera
4. Gahunda yo Gukemura Ibibazo mu buryo Busanzwe
Iyo habayeho inenge kenshi, koresha ubu buryo bwo gusuzuma bukurikije gahunda:
Intambwe ya 1: Kugenzura ibidukikije

Umwanzuro
Uduce tw'imigozi, imiyoboro igabanuka, n'ibimenyetso by'amazi si inenge zihariye - ni byoibimenyetso by'ubusumbane mu miterere y'umubiri, imikorere, n'imiterere y'ibihumyo.
Gukora polyurethane ihamye bisaba kugenzura neza ibi bikurikira:
- Ubwiza bw'ibikoresho fatizo
- Imiterere y'ibisubizo
- Sisitemu ya Catalysis
- Ubwubatsi bw'ibimera
- Imyitwarire mu mikorere
Kugira ngo imikorere ihamye kandi igabanuke, hakozwe nezaumuti wa sisitemu ya polyurethaneni ngombwa.
Hamagara itsinda ryacu rya tekiniki kugira ngo umenye uburyo bwo kunoza imiterere y’ibicuruzwa, guhitamo katalyst, no gushyigikira sisitemu:
