Incazelo Yomkhiqizo

I-MSI (PTSI), i-p-toluenesulfonyl isocyanate, i-monoisocyanate esetshenziswa kakhulu, inhlanganisela esabela kakhulu esetshenziswa kabanzi njenge-ejenti yokuqeda amanzi emikhiqizweni yamakhemikhali, njengezinyibilikisi, izigcwalisi, imibala kanye nezindawo ze-pitch tar. Njengoba iyisithako sokususa umswakama wezingubo ze-polyurethane (PU) ezisekelwe kwi-solvent, ama-sealant, ama-adhesive kanye nanjengengxenye yamakhemikhali ahlukahlukene abalulekile embonini.

I-p-toluenesulfonyl isocyanate (i-PTSI) ivimbela ukusabela okungafuneki ngaphambi kwesikhathi komdwebo kanye nopende, ngakho-ke, ivumela abakhiqizi ukuthi bakhiqize ama-polyurethane asezingeni eliphezulu. Ngokusebenzisa i-PTSI ekukhiqizeni upende we-polyurethane, ukulahleka kwe-gloss, yellowing kanye ne-reactive foam okubangelwa ubuso obumanzi ohlelweni konke kuyancishiswa. I-p-toluenesulfonyl isocyanate ingaba futhi isithasiselo sokuzinzisa sezinto eziqeda umswakama ukuvimbela ukuwohloka noma/nokuguquka kombala ngenkathi igcinwa.

Ukusebenza kanye nezici

I-MSI (PTSI) isabela namanzi, ikhipha i-carbon dioxide futhi iholele ekwakhekeni kwemikhiqizo yokusabela encibilikayo ekwakhiweni kopende okuvamile. Cishe u-12g we-stabilizer uyadingeka ngokombono ukuze kusetshenziswe i-1g yamanzi. Nokho, ulwazi luye lwabonisa ukuthi ukusabela kusebenza kangcono uma kukhona i-MSI(PTSI) eyengeziwe. Ukuhambisana nezihlanganisi zopende kufanele kuhlolwe njalo kusengaphambili.

Kunconywa ukuthi i-p-toluenesulfonyl isocyanate isetshenziswe njengesiqedi seketanga ngesikhathi se-polymerization kanye nokususa amaqembu asebenzayo angasebenzi kahle ezintweni zokusetshenziswa ze-PU. Ezimbozweni ze-PU ze-coal tar, i-MSI ingasetshenziswa ukuqeda ama-amine namaqembu asebenzayo e-OH futhi isuse amanzi ku-tar ukuze igweme ukuqhuma kwegwebu kanye ne-gelation ngaphambi kwesikhathi lapho i-tar ixutshwa ne-PU prepolymer.

Izici:

- Iqeda imiphumela yomswakama futhi ivimbele izinkinga ezihlobene nomswakama ezimbozweni ze-polyurethane

- I-viscosity ephansi, i-isocyanate esebenza nge-monofunctional ephendula ngamakhemikhali namanzi ukuze yakhe i-amide engasebenzi kahle

- Isetshenziselwa ukuqeda amanzi emzimbeni wezinyibilikisi, izigcwalisi, imibala kanye nama-tar e-bituminous

- Kuthuthukisa ukuzinza kokugcinwa kwama-diisocyanates ekuboleni nasekushintsheni kombala

- Isusa umswakama ofakwe izinyibilikisi, imibala, kanye nezigcwalisi ezinhlelweni ze-PU ze-single-component kanye ne-Dual-component

Isicelo

I-MSI (PTSI) isetshenziswa njengesiqinisi sezinto eziqeda umswakama. Ivimbela ukusabela okungathandeki kwangaphambi kwesikhathi komdwebo kanye nopende. I-p-toluenesulfonyl isocyanat ivame ukusetshenziswa njengezindawo ezilandelayo:

- Izinamathiseli ze-polyurethane ezinengxenye eyodwa kanye nezinezingxenye ezimbili kanye nezinamathiseli.

- Upende we-polyurethane onengxenye eyodwa kanye nowezingxenye ezimbili.

- Izinyibilikisi

- Imibala

- Ama-Filler

- Ama-reagent

Ukupakisha Nokugcina Izinto

Ukupakisha: 20kgs, 180/isigubhu sensimbi.

Ukugcinwa Nokuthuthwa: I-PTSI iyazwela umswakama ngakho-ke kufanele igcinwe njalo ezitsheni zokuqala ezivalwe kahle emazingeni okushisa aphakathi kuka-5°C no-30°C. Uma sezivuliwe, izitsha kufanele zivalwe kabusha ngokushesha ngemva kokususwa ngakunye komkhiqizo. Gcina kude notshwala, izisekelo eziqinile, ama-amine, ama-oxidizing agents aqinile.

Isikhathi sokuphila: Izinyanga ezi-6 kusukela ngosuku lokukhiqizwa.
