I-PU FOAM uhlobo lwenjoloba
, eyaziwa nangokuthi i-vonge rubber, ebonakala yimodeli ye-foam engawonakele, injoloba evundlekeni ngesakhiwo se-spongy porous. Kunezimbobo ezivulekile, izimbobo ezivalekile, izimbobo ezixubile nezimbobo ezincane, kungenziwa kube yinjoloba ethambile noma imikhiqizo enjoloba kanzima. Isisindo esikhanyayo, esithambile, esilinganayo, asilula ukushisa. I-Foam inemisebenzi yobufakazi obushaqisayo, ukuncipha okushaqisayo, ukufakwa kokushisa, ukufakwa okuzwakalayo nokunye. I-Foam eyenziwe ngerabha yokwenziwa nayo inezimpawu zokumelana kawoyela, ukumelana nokuguga kanye nokumelana kwamakhemikhali. Isetshenziswa kakhulu ezimotweni, ezindizeni, amakhemikhali, izidingo zansuku zonke kanye nezinye izimboni, ezisetshenziswa njengokufakwa kwemishini, ukufakwa kwemishini, kanye nemishini yezokwelapha, imishini yezempilo, imikhiqizo yezemidlalo nokunye. I-polyurethane ingenziwa ngerabha eluhlaza nge-ejenti ye-foaming (njenge-ammonium carbonate, urea, azo disobutronitile, njll.)
Izihubi
Isifutho se-polyurethane Foam
ingasetshenziswa ku
amasela
, imikhiqizo yasendlini kanye ne-chemistry yendiza. Kulezi zici kungadlala ukufakwa okushisa, ukuqina komzimba kanye nokufakelwa okuzwakalayo, futhi i-foam yekhwalithi enhle inobungani bemvelo, ngemuva kokufuna ukuxhumana nabantu, ngeke kube nemiphumela emibi. Ngaphezu kwalokho, igwebu linomphumela oqinile wokunamathela. Ngemuva kokufakwa ekwenzeni izimoto, ngeke iwe kalula. Ngaphezu kwalokho, kungagcina impahla enhle yokunamathela ekushiseni okuphezulu namanzi, futhi akulula ukuncibilika.

ngumkhiqizo wokwenziwa we
Izinto zokusetshenziswa kwezimboni zezimboni
. Isebenzisa i-solvent exubile ye-benzene. Kuyinto
-phathelene nemvelo
umkhiqizo onobungane ngaphandle kwephunga elikhethekile,
ukoma okusheshayo
, ukunamathela okusheshayo, namanzi amahle nokumelana nesimo sezulu.
Izinzuzo zengcindezi enhle
Uhla olubanzi lwezinkambu
I-Polyurethane Foulk ephezulu ephezulu ingahle isetshenziswe ekukhiqizeni umatilasi, imikhiqizo yokuhlanza, amadivaysi ezokwelapha, kanye nezimpahla zezemidlalo. Lezi zinkambu zinezidingo eziqinile kakhulu ku-Foam glue futhi zidinga ukulawula kahle ikhwalithi. Ngakho-ke, kuyadingeka ukubambisana nemikhiqizo enesiqinisekiso sekhwalithi ukuqinisekisa ikhwalithi. Sinikeza ngezixazululo zohlelo lokusebenza lwe-FOAM ngokwezifiso ngohlobo olubanzi lokusetshenziswa, olungasetshenziswa emandleni amasha, ezempi, ezokwelapha, ukuhambisa, ama-elekthronikhi, izimoto, izinsimbi zejubane, izinsimbi ezisheshayo.
Ukusebenza okuphezulu kokuphepha
Ngokuvamile, ukumelana nengcindezi ye-pu yokumelana kakhulu, ikhwalithi engcono. Kepha ukwakhiwa kwezidingo ze-polyurethane foam sealant aziphakeme kangako, ngokwanele ukuvikela uhlaka lomnyango ekuweni. Ingcindezi yayo imvamisa phakathi kwe-100Kap ne-180kpa, isisindo esiphakathi.
