    Ibisobanuro

    MOFAN ML90 ni methylal ifite ubuziranenge burenze 99.5%, ni igikoresho gikoreshwa mu gushyushya ibidukikije kandi gihendutse gifite imikorere myiza ya tekiniki. Ivanze na polyols, ishobora gutwika. Ishobora gukoreshwa nk'igikoresho cyonyine gikoreshwa mu gushyushya ibyuma, ariko kandi izana inyungu iyo ihujwe n'ibindi bikoresho byose bikoreshwa mu gushyushya ibyuma.

    Ubwiza n'imikorere bitagira urugero

    MOFAN ML90 iragaragara ku isoko kubera ubuziranenge bwayo budasanzwe. Iyi methylal ifite ubuziranenge bwinshi si ibicuruzwa gusa; ni igisubizo cyagenewe abakora ibintu bashyira imbere ubuziranenge n'ubudahangarwa. Ubuziranenge buhebuje bwa MOFAN ML90 butuma yuzuza ibisabwa bikomeye mu ikoreshwa ry'ifuro ritandukanye, bigatanga umusaruro uhoraho kandi bikanongera ubwiza bw'umusaruro wa nyuma muri rusange.

    Umukozi ushinzwe ibidukikije n'ubukungu

    Mu gihe inganda ziharanira kugabanya ingaruka mbi ku bidukikije, MOFAN ML90 igaragara nk'amahitamo ajyanye n'ibidukikije n'ubukungu. Uburyo bwayo butuma habaho kugenzura neza uburyo umuriro utwika iyo uvanze na polyols, bigatuma iba amahitamo yizewe ku bikorwa bitandukanye. Ubu buryo bworoshye busobanura ko MOFAN ML90 ishobora gukoreshwa nk'igikoresho cyonyine cyo gusohora mu buryo bw'umwimerere cyangwa hamwe n'ibindi bikoresho byo gusohora, bigaha abakora ubworoherane bakeneye kugira ngo barusheho kunoza imikorere yabo.

    Ibyiza

    ● Ntishobora gushya cyane ugereranyije na n-Pentane na Isopentane kuko byoroshye gushya cyane. Uruvange rwa polyols rufite Methylal ikoreshwa mu gushyushya polyurethane rugaragaza ubushobozi bwo gushyushya cyane.

    ● Ifite imiterere myiza y’uburozi bw’ibidukikije.

    ● GWP ni 3/5 gusa bya GWP ya Pentanes.

    ● Ntabwo izashira amazi mu mwaka umwe ku rugero rwa pH ruri hejuru ya 4 za polyols zivanze.

    ● Ishobora kuvangwa neza na polyol zose, harimo na polyols zihumura neza.

    ● Ni uburyo bugabanya ubukana bukomeye. Kugabanuka biterwa n'ubukana bwa polyol ubwayo: uko irushaho kuba nyinshiubushyuhe bw'izuba, niko kugabanuka kwaryo kwiyongera.

    ● Ubushobozi bwo gusohora ifuro bwa wt 1 yongewemo bungana na 1.7 ~ 1.9wt HCFC-141B.

    Ibibazo Bikunze Kubazwa

    Nkora ifuro rya polyurethane ry’uruhu ry’ibikoresho by’imodoka (amapine y’imodoka, aho gushyira amaboko). Ese MOFAN ML90 ishobora gukoreshwa nk'ikintu cyonyine gitanga umwuka wo guhumeka?

    Yego, ML90 (methyl nyinshi) ishobora gukoreshwa nk'ikintu cyonyine gitanga umwuka mwiza, gitanga imiterere myiza y'ubuso n'imiterere imwe y'uturemangingo hamwe n'ubucucike buke.

    Uburyo bwanjye bwo gushushanya ifuro rigikomeye bukoresha HCFC-141b burimo gukurwaho. Ese ML90 ishobora kuyisimbura?

    Yego, ML90 ni ubundi buryo bwo kurengera ibidukikije kandi buhendutse. Ubushyuhe bwayo bugera kuri ~42°C n'ubushobozi bwayo bwo gushyushya birasa, bisaba ko habaho gukosora bike cyane.

    Ni iki gipimo gisanzwe cya ML90 mu ifuro rihindagurika ku bikoresho byo mu nzu?

    2–8 phr bitewe n'ubucucike bw'intego; urugero rwo hejuru rugabanya ubucucike ariko rushobora kongera ubworoherane bw'ifuro. Vanga n'amazi kugira ngo uturemangingo twuguruke neza.

    Ese ML90 ishobora kuvangwa n'ibindi bintu bihuha (urugero: amazi, cyclopentane, HFC 245fa)?

    Yego, ikorana neza n'ibintu byose bisanzwe bikoreshwa mu gushyushya, ikongera ubushobozi bwo gushonga muri polyols kandi ikagabanya ingano y'ibikoresho bikoreshwa mu gushyushya bikenerwa.

    Ifuro ryanjye rito cyane ryo gupakira rifite ubushobozi buke bwo kugabanya ubukana bw'amazi gusa. ML90 yagufasha ite?

    Kongeramo 3–5 phr ML90 bigabanya urugero rw'amazi akenewe, bigabanya imbere mu kirere kandi bikongera ubuziranenge bw'ibipimo.

    Ese MOFAN ML90 irashya? Wayifata ute mu buryo bwizewe mu ruganda rukora ifuro?

    Yego, methylal irashya. Koresha ibikoresho bikwiye byo guhumeka, gusiga hasi, no kwirinda guturika; ishobora kuvangwa neza na polyols kugira ngo igabanye ubushyuhe.

    Ifuro ryanjye rikomeye ritera umwanda rifite ubuso bubi bitewe n'umwuka wihuse w'ikintu gihumeka. Ese ML90 izabinoza?

    Ubushyuhe bwayo buri ku rugero rwo hagati no gushonga neza muri polyol bigabanya kwaguka mbere yo kwaguka, bigatanga ubuso bworoshye.

    Ni iyihe nyungu ya ML90 ugereranyije na acetone cyangwa ibindi bintu bihumeka mu ifuro rihindagurika?

    ML90 ifite impumuro nkeya, irashonga neza, kandi itanga uturemangingo twiza; kandi ntitera ibara ry'ifuro.

    Ese ML90 ishobora gukoreshwa muri polyurethane elastomers kugira ngo igabanye ubucucike?

    Yego, kuri elastomer ntoya (urugero, inkweto zo hejuru), koresha 1–3 phr ML90 hamwe n'amazi; bifasha mu kugabanya ubucucike nta turemangingo tunini.

    Ni ubuhe buziranenge bwa MOFAN ML90 kandi bugira izihe ngaruka ku bwiza bw'ifuro?

    Ubuziranenge bwa ≥99.5% butuma habaho imikorere ihoraho, ingaruka nke ku ruhu, kandi impumuro nke isigara mu ifuro ryarangiye.
