Yintoni izixhobo ze-pu?
Inkcazo esisiseko yeZixhobo zePu
I-PU imele i-Polyrerthane, izinto zepolymer ezisetyenziswa ngokubanzi kumashishini ahlukeneyo. I-Polyreurthane iveliswa yindlela yokuphendula yemichiza phakathi kwe-idoncyanate kunye ne-polyol, kwaye inoluhlu olubanzi lweepropathi zomzimba kunye nekhemikhali. Kuba i-PU inokuba neepropathi zayo ihlengahlengiswe ngokutshintsha kobume bayo, isetyenziswa kuluhlu olubanzi lwezicelo, ukusuka kwi-APREAREL kwizixhobo zokwakha.
Ukuhlelwa kunye neepropathi ze-pu
I-Polyreurthane inokuchazwa kwiifom ezahlukeneyo, kubandakanya i-foam eqinileyo, i-fills eziguquguqukayo, i-Elastomers, i-ProATESS kunye nababukeli. I-foam ezingqongqo zisetyenziselwa ukufakelwa kunye neephaneli zokwakha, ngelixa i-Flesx eguqukayo isetyenziswa ngokubanzi kwifanitshala, izihlalo zemoto kunye netrayi. I-Elastomers, kwelinye icala, zibonisa irabha-njenge-elasticity kwaye isetyenziselwa izithsaba, amatayara njalo njalo. Ngenxa yobudala obulungileyo, ukumelana ne-abrasion, ukuchasana kweoyile kunye nokuxhathisa okwaluphala, i-PU ibonisa intsebenzo egqwesileyo kwizicelo ezahlukeneyo.
Ukusetyenziswa kwe-pu kwimizi-mveliso eyahlukeneyo
I-Polyurrethane inoluhlu olubanzi lwezicelo kwimimandla eyahlukeneyo. Umzekelo, kwishishini lendwangu, i-PU isetyenziswa ngokuveliswa kwesikhumba esenziwe ngesikhumba, enombhalo ofanayo wesikhumba kodwa inesidima kwaye kube lula ukuyigcina. Kumzi-mveliso wokwakha, i-guam isetyenziswa njengezixhobo zokufakwa ezikumgangatho ophezulu, ezithandwayo ngokuxhaphaza okuphantsi kwengqondo kunye nokunganyangwa okuhle. Kumzi-mveliso we-Automotive, izixhobo ze-PU zisetyenziselwa ukwenza i-foams yesihlalo kunye ne-trim yangaphakathi yeTrim njengoko inika intuthuzelo kunye nokuqina.
Ubuhlobo bokusingqongileyo kunye nokuzinza kwezinto ze-PU
Njengoko ukunyuka kokusingqongileyo, ukuzinza kwezinto ze-PU kube yeyona nto iphambili. Ngokwesiko, ezinye iikhemikhali eziyingozi zinokusetyenziswa kwimveliso ye-PU, kodwa kwiminyaka yakutshanje, eli shishini liphuhlise iinkqubo zokuvelisa ubuhlobo bendalo njengokuthi ze-polyurethane esekwe emanzini kunye nokusetyenziswa kwezinto ezingafunekiyo. Ezi zinto zintsha ze-pune azinciphisi kuphela impembelelo kwindalo esingqongileyo, kodwa zikhuthaza ukhuseleko lwemveliso kunye nokuzinza.
Isishwankathelo
Yintoni izixhobo ze-pu? Yinto esebenzayo, esebenza nzima kakhulu esetyenziswa ngokubanzi kwimizi-mveliso eyahlukeneyo. Enoba kwi-atheresorel, ulwakhiwo, izithuthi, okanye ukukhuselwa kwendalo, i-PU ithandwa ngenxa yeepropathi zayo ezilungileyo kakhulu. Ngokuqhubela phambili kwetekhnoloji kunye nokuphuculwa kweemfuno zoKhuseleko lweNkcubeko yezeNdalo, indawo yokusebenza kunye nenqanaba lobugcisa lezinto ze-PU ziya kuqhubeka nokwandisa kwaye ziphucule.
