Ukuthelekisa ukuSebenza kweZithuthi zeSilicone zeZithuthi kunye neMveli yeMveli eyenziweyo
I. Ukusebenza okugqwesileyo kokusiNgqongileyo
Izinto eziqhelekileyo zePU kunye nePVC zibonisa imiba ethile yokusingqongileyo ngexesha lemveliso kunye nokusetyenziswa. I-PVC icutshungulwa ngeekhemikhali ezahlukeneyo, kuquka iiplastiki. Ezinye iiplasticizers, ezinje ngephthalates, zinokuguquguquka kumaqondo obushushu aphezulu ngaphakathi kwesithuthi, zichaphazele kakubi umgangatho womoya kwaye zibeke emngciphekweni impilo yabaqhubi nabakhweli. Ngenxa yokwakheka kweekhemikhali eziyinkimbinkimbi, izinto ze-PU zinzima ukuthotywa emva kokulahlwa, okubangelwa ngumthwalo wexesha elide lokusingqongileyo.
Izinto zeSilicone, kwelinye icala, zibonisa ukusebenza kakuhle kokusingqongileyo. Izinto zabo ezikrwada zitsalwa kwi-silicon ore yendalo, kwaye inkqubo yokuvelisa ayinyibilikiyo, iqinisekisa ii-VOCs eziphantsi kakhulu kumthombo. Oku akuhlangabezani kuphela nemfuno yangoku yabathengi yohambo oluluhlaza kunye nokusingqongileyo kodwa kunciphisa ukukhutshwa kongcoliseko ngexesha lemveliso yemoto. Emva kokuba isithuthi sichithwa, izinto ze-silicone zilula ukuthotywa, ukunciphisa impembelelo yokusingqongileyo kunye negalelo kuphuhliso oluzinzileyo.
II. UkuGqibela okugqwesileyo kunye nokuzinza
Izinto zangaphakathi zeemoto zihlala ziphantsi kweemeko ezinzima ezinje ngamaqondo obushushu aphezulu, imitha ye-UV, kunye nokufuma, kubeka iimfuno eziphakamileyo kakhulu ekomeleleni kwezinto. Izinto ze-PU kunye ne-PVC zemveli ziyakwazi ukuguga, ukuqina, kunye nokuqhekeka phantsi kwezi mpembelelo zokusingqongileyo.
Izinto zeSilicone, kwelinye icala, zibonelela ngokumelana nemozulu entle kunye nokuzinza kweekhemikhali. Izixhobo zeSilicone ezisetyenziswa kwizihlalo kunye nezixhobo zangaphakathi zigcina iipropathi ezibalaseleyo zomzimba nasemva kokuvezwa ixesha elide kumaqondo obushushu aphezulu. Ubume bemichiza ye-Silicone bubonelela nge-UV kunye nokuchasana kwe-oxidation, ukuchasana ngokufanelekileyo nomonakalo wokusingqongileyo, ukwandisa kakhulu ixesha lokuphila langaphakathi kunye nokunciphisa iindleko zokugcina ngexesha lokusetyenziswa kwesithuthi.
Ukhuseleko oluPhezulu
Kwimeko yongquzulwano okanye enye ingozi yemoto, ukhuseleko lwezixhobo zangaphakathi lubalulekile. Izinto eziqhelekileyo ze-PU kunye ne-PVC zinokukhupha izixa ezikhulu zeegesi ezinobuthi xa zitshiswa. Ngokomzekelo, ukutshiswa kwe-PVC kuvelisa iigesi ezinobungozi ezifana ne-hydrogen chloride, ebeka ingozi enkulu kukhuseleko lwabahlali bezithuthi.
Izixhobo zeSilicone zineempawu ezintle zokunqanda amadangatye, zicothisa ngokufanelekileyo ukusasazeka komlilo kwaye zivelise umsi omncinci kunye neegesi ezinetyhefu xa zitshiswa.
Okwesithathu, ubuchule obuphezulu kunye nentuthuzelo
Ukuqhuba intuthuzelo luphawu oluphambili lomgangatho weemoto, kwaye imvakalelo ebambekayo yezinto zangaphakathi ichaphazela ngqo le ntuthuzelo. Iimathiriyeli ze-PU kunye ne-PVC yesiNtu zihlala zinemvakalelo erhabaxa, ziswele ukuthamba kunye nokucokisa, zibenza bangabinakho ukunika iprimiyamu kunye namava atofotofo.
Izixhobo zeSilicone zinika imvakalelo ethambileyo kunye negudileyo ebambekayo, idala umoya okhululekileyo kunye nobutofotofo ngaphakathi kwesithuthi. Isikhumba seSilicone, esisetyenziswa kuyilo lwangaphakathi, sinikezela ngobume obucekeceke obuvakala njengesikhumba sendalo, siphucula umgangatho uwonke wemoto yangaphakathi. Ngaphaya koko, ukuphefumla okugqwesileyo kwezixhobo ze-silicone kunceda ukuphucula intuthuzelo yokuqhuba kunye nokunciphisa imvakalelo yokuxinana okubangelwa kukukhwela ixesha elide.
IV. Ukusebenza koKhuseleko
1. UkuBuyiswa komlilo
I-Silicone yesikhumba ine-Limiting Oxygen Index (LOI) ye-32%, iyazicima ngaphakathi kwemizuzwana ye-1.2 xa idibene nomlilo, inobunzima bomsi we-12, kwaye iyanciphisa ukukhutshwa kwegesi enetyhefu nge-76%. Isikhumba sokwenyani sesintu sikhupha ihydrogen cyanide xa sitshisiwe, ngelixa iPVC ikhupha ihydrogen chloride.
2. Ukhuseleko lwendalo
-Ifumene i-ISO 18184 isatifikethi se-antiviral, kunye ne-99.9% yezinga lokungasebenzi ngokuchasene ne-H1N1 kunye ne-cytotoxicity ephantsi kakhulu, eyenza ilungele iikhabhi zonyango kunye neemveliso zabantwana.
V. Intuthuzelo kunye nobuhle
1. Ukubamba kunye nokuphefumla
-I-Silicone ivakalelwa kwaye isondele kwisikhumba sangempela, kwaye inokuphefumula okungcono kunePVC; I-PU yesiko ithambile kodwa ithande ukuba lukhuni emva kokusetyenziswa kwexesha elide.
2. Uyilo olubhetyebhetye*
- Izinto ezintsonkothileyo ezinjengemizobo ye-inki zinokufakwa, kodwa ukhetho lombala lunqongophele (kuba izinto ezingasebenziyo kunzima ukuzifaka umbala); ufele lwemveli lutyebile ngombala kodwa kulula ukubuna.
