Ndingazi Njani Ukuba I-Foam Ivaliwe?

Iifoam zePolyurethane zisetyenziswa kakhulu kwiindlela ezahlukeneyo zokusebenza ngenxa yeempawu zazo ezibalaseleyo zokuthintela ubushushu kunye namandla olwakhiwo. Uhlobo oluphambili lwefoam ye-polyurethane yifoam yeseli evaliweyo, eyaziwa ngokuba lukhuni kwayo kunye nokuqina kwayo. Njengomthengisi wee-catalysts ze-polyurethane, siyayiqonda ukubaluleka kokuqonda iimpawu kunye nokusetyenziswa kwefoam yeseli evaliweyo, kunye nendima yee-catalysts ezithile ezifana ne-MXC-C15 kunye ne-MXC-A33 kwimveliso yazo.

Ukuchonga iFoam yeeSeli eziValiweyo

Ifoam yeseli evaliweyo yahlulwe ngesakhiwo sayo esixineneyo nesincinci, apho iseli nganye ivalwe ngokupheleleyo kwaye ihlanganiswe ndawonye. Esi sakhiwo sikhethekileyo sinika ifoam yeseli evaliweyo iimpawu ezahlukeneyo:

1. Ubuninzi kunye nobunzima: Ifoam evaliweyo ixinene kakhulu kwaye inzima xa ithelekiswa nefoam evulekileyo. Olu xinano luphezulu lunegalelo kwiipropati zalo zokukhusela ubushushu kunye nokuqina kwesakhiwo.

2. Ukumelana Namanzi: Enye yezona zinto zibalulekileyo kwi-closed-cell foam kukungakwazi kwayo ukufunxa amanzi. Ngokungafaniyo ne-open-cell foam, i-closed-cell foam ayifunxi manzi, nto leyo eyenza ukuba ilungele ukusetyenziswa apho ukumelana nokufuma kubalulekile.

3. Ukufakwa kobushushu: Ifoam evaliweyo inika ukugcinwa kobushushu okugqwesileyo ngenxa yesakhiwo sayo esincinci seseli. Inexabiso eliphezulu le-R, oko kuthetha ukuba isebenza ngakumbi ekuthinteleni ukudluliselwa kobushushu.

4. Ukuqina: Ukuqina kwefoam kuyenza ifaneleke ukusetyenziswa xa ifuna inkxaso eyongezelelweyo yolwakhiwo. Igcina imo yayo phantsi koxinzelelo kwaye inika umphezulu ozinzileyo.

Ukusetyenziswa kweFoam yeSeli eValiweyo

Ifoam ye-polyurethane evaliweyo isetyenziswa kumashishini ahlukeneyo ngenxa yeempawu zayo eziluncedo. Ezinye zezicelo eziqhelekileyo ziquka:

- Ukuthintela Izakhiwo: Ifoam evaliweyo isetyenziswa kakhulu ekwakheni ukuthintela iindonga, uphahla, kunye neziseko. Ixabiso layo eliphezulu le-R linceda ukugcina amaqondo obushushu angaphakathi, linciphisa iindleko zamandla.

- Izixhobo zokudada: Ngenxa yokuba zidada kwaye zimelana namanzi, i-closed-cell foam isetyenziswa ekwenzeni ii-life vests, izixhobo zokudada, kunye nezinye izixhobo zokudada.

- Ukupakisha: Ukuqina kwefoam kunye neempawu zokukhusela zenza ukuba ilungele ukupakisha izinto ezibuthathaka, ukuqinisekisa ukuba zihlala zikhuselekile ngexesha lokuthuthwa.

- Iimoto: Kwishishini leemoto, i-closed-cell foam isetyenziselwa ukuthintela isandi kunye nokukhusela ubushushu kwizithuthi.

Indima yeeCatalysts kwiMveliso yeFoam eValiweyo

IiCatalysts zidlala indima ebalulekileyo ekuvelisweni kwefoam ye-polyurethane evaliweyo, zichaphazela iipropati kunye nokusebenza kwefoam. IiCatalysts ezithile, ezifana neMXC-C15 kunye neMXC-A33, zisetyenziselwa ukuphucula iimpawu zefoam:

- I-MXC-C15: Le catalyst isetyenziswa kakhulu kwizicelo zefoam eziguquguqukayo neziguquguqukayo kancinci kunye nefoam eqinileyo. Ingasetyenziswa nakwifoam zebloko yepolyether kunye neCASE.

- I-MXC-A33: Esi sincedisi sisetyenziselwa igwebu elithambileyo, igwebu eliqinileyo, igwebu eliqinileyo. Ingasetyenziselwa nezinye izinyibilikisi ezinyibilikayo, ezifana ne-MEG, i-DEG, i-BDO, njl.njl., kwizicelo ezahlukeneyo..

Ukuqonda iipropati kunye nokusetyenziswa kwefoam ye-polyurethane evaliweyo, kunye nendima yee-catalysts ezithile, kubalulekile kubavelisi nakubasebenzisi ngokufanayo. Ngokukhetha ii-catalysts ezifanelekileyo, ezifana ne-MXC-C15 kunye ne-MXC-A33, abavelisi banokuqinisekisa ukuba ifoam iyahlangabezana nemigangatho efunekayo kwizicelo ezahlukeneyo, inikezela ngezisombululo ezinokuthenjwa nezisebenza kakuhle.
