Kugwiritsa Ntchito Polyurethane

Polyurethane ingagwiritsidwe ntchito popanga mapulasitiki, mphira, ulusi, thovu lolimba komanso losinthasintha, zomatira ndi zokutira, etc. Ikhoza kugwiritsidwa ntchito m'madera osiyanasiyana a moyo wa anthu ndipo imakhala ndi ntchito zambiri.

1. Chithovu cha polyurethane:

Amagawidwa mu thovu lolimba la polyurethane, thovu lolimba la polyurethane ndi thovu losinthika la polyurethane.Chithovu cholimba cha polyurethane chimagwiritsidwa ntchito makamaka pomanga zida zotchinjiriza, zida zotenthetsera zotenthetsera (mapaipi, etc., kutchinjiriza kwamafuta ndi ntchito yatsiku ndi tsiku) (mabedi, sofa, etc., matiresi, mafiriji, zoziziritsira mpweya, etc. ma surfboards, etc. core materials, and Transportation (magalimoto, ndege, sitima zapanjanji, ma cushion, kudenga ndi zipangizo zina).

2. Polyurethane elastomer:

Polyurethane elastomer ili ndi ubwino wa mphamvu yabwino yamakokedwe, kugwetsa mphamvu, kukana kukhudzidwa, kukana kwa abrasion, kukana kwa nyengo, kukana kwa hydrolysis, kukana mafuta ndi zina zotero.Amagwiritsidwa ntchito makamaka popangira zida zokutira (monga chitetezo cha ma hose, ma washer, matayala, zodzigudubuza, magiya, mapaipi, ndi zina), zoteteza, nsapato, matayala olimba.

3. Polyurethane madzi zinthu:

Zinthu zopanda madzi za polyurethane ndizosavuta kugwiritsa ntchito.Ikhoza kusakanikirana pa malo ndikuchiritsidwa ndi kutentha kwabwino ndi chinyezi pambuyo popaka, ndiyeno wosanjikiza madzi opanda seams, elasticity mphira ndi ntchito zabwino angapezeke.Ndipo zosavuta kukonza pambuyo kuwonongeka.Nthawi zambiri amagwiritsidwa ntchito ngati zida zomangira, njanji ndi zida zam'munda, njanji zothamanga, zida zapansi papaki, mafelemu azenera otenthetsera, etc.

4. Chophimba cha polyurethane:

Kupaka kwa polyurethane kumakhala ndi zomatira zolimba, ndipo filimu yokutira imakhala yabwino kwambiri kukana kuvala, kukana madzi komanso kukana mankhwala.Amagwiritsidwa ntchito makamaka pakuyika mipando, zokutira zomangira ndi inki zosindikizira zamakampani.

5. Zomatira za polyurethane:

Kuchita kwa mankhwala ochiritsidwa kungasinthidwe mwa kusintha chiŵerengero cha isocyanate ndi polyol, kuti athe kukwaniritsa zomatira kwambiri ku gawo lapansi, kukana madzi abwino, kukana mafuta ndi kukana mankhwala.Zomatira za polyurethane zimagwiritsidwa ntchito kwambiri pakuyika, kumanga, matabwa, magalimoto, kupanga nsapato ndi mafakitale ena.

6. Zida zamankhwala:

Polyurethane ili ndi biocompatibility yabwino kwambiri, chifukwa chake imagwiritsidwa ntchito pang'onopang'ono ngati zida zamankhwala.Itha kugwiritsidwa ntchito popanga ma pacemakers opangira mtima, mitsempha yamagazi yokumba, mafupa opangira, am'mero ​​opangira, impso zopanga, nembanemba za dialysis, etc.
