Kwihlabathi elintsonkothileyo loyilo lwangaphakathi kunye nezixhobo zokwakha, iphepha lodonga elinefoam liyila indawo ngenxa yobume balo obukhethekileyo, ukuthintela isandi, kunye nokuguquguquka kobuhle. Eyona nto iphambili ekusebenzeni kwalo okugqwesileyo kukho into eqhele ukuhoywa kodwa eyimfuneko: iziqinisi zolwelo. Ezi zongezo zikhethekileyo zisebenza njengesiseko sokuqinisekisa ukuqina kwephepha lodonga elinefoam, ukuqhubekeka kokusebenza, kunye nokuhambelana nokusingqongileyo. Makhe sihlolisise imisebenzi ebalulekileyo ebangela ukuba iphepha lodonga elinefoam lihlale ixesha elide, lisebenze kakuhle, kwaye lihambelane nokusingqongileyo. Makhe sihlolisise imisebenzi ebalulekileyo ebangela ukubaisizinzisi sobushushu sePVC elulwelokubalulekile ekuvelisweni nasekusetyenzisweni kwephepha lodonga elinegwebu.
1. Uzinzo lobushushu: Ukukhusela kwinguquko ebangelwa bubushushu
Ukuveliswa kwephepha lodonga elinegwebu kubandakanya iinkqubo zobushushu obuphezulu, ezinje ngokuphuma kunye nokuhlelwa kwekhalenda, ezinokufikelela kumaqondo obushushu afikelela kwi-200°C. Ngexesha lale misebenzi, i-polymer matrix yephepha lodonga isengozini yokuwohloka kobushushu, okukhokelela kwimiba efana nokudumba komphezulu, ukugqwetheka kombala, kunye nobuthathaka besakhiwo. Iziqinisi zolwelo zisebenza njengabalindi bobushushu, zithintela ii-free radicals eziveliswa kukuvezwa kobushushu. Uphando oluvela kwi-Wallcovering Manufacturers Association lubonisa ukuba ngaphandle kweziqinisi ezifanelekileyo, iisampulu zephepha lodonga ezinegwebu zifumana ukwehla kwama-40% kwamandla okutsalwa emva kwemizuzu eli-15 kuphela kwi-180°C. Ngokwahlukileyo koko, iphepha lodonga eline-optimizedisizinzisi solweloIifomyula zigcina ngaphezulu kwe-85% yamandla azo okuqala, ziqinisekisa ukuba izinto zigcina imo yazo kunye nokuthembeka kwazo ngexesha lokufakelwa kunye nokusetyenziswa ixesha elide, nakwiindawo ezinokuguquguquka okuphezulu kobushushu, njengeekhitshi okanye amagumbi akhanyiswe lilanga.
2. Ukugcinwa kwesakhiwo seFoam: Ukuphucula ukufana kweeseli kunye nokuzinza
Ubume obahlukileyo kunye nobunzima bephepha lodonga elinogwebu buxhomekeke kwi-foam yeselula eyakhiwe kakuhle. Iziqinisi zolwelo zidlala indima ebalulekileyo ekulawuleni inkqubo yokwenziwa kwegwebu, ukuqinisekisa ukwakheka kwezakhiwo ezifanayo, ezivaliweyo. Ngokulawula ukwakheka kunye nokukhula kwamaqamza egesi, ezi zongezo zithintela imiba efana nokuwa kweeseli, ukuhlangana, okanye ukusasazwa okungalinganiyo. Umzekelo, kuphononongo oluthelekisayo kwiphepha lodonga elinogwebu elisekelwe kwi-PVC, iisampulu ezineziqinisi zolwelo zibonise ukonyuka kwe-30% kuxinano lweeseli kunye nokwehla kwe-25% kokwahluka kobukhulu beeseli xa kuthelekiswa nezo zingenayo. Oku kuphumela kukwakheka komphezulu okuhlala kufana, iipropati zokukhusela eziphuculweyo, kunye namandla oomatshini aphuculweyo, okwenza iphepha lodonga likwazi ukumelana ngakumbi neempembelelo kunye nokuguguleka.
Ishishini lephepha lodonga lisesicongweni soguquko lwetekhnoloji, kunye nezinto zokuqinisa ulwelo eziphambili ekuveliseni izinto ezintsha. Abaphandi bayaphandaiifomyula zokuzinzisa ezisebenza ngeendlela ezininziezidibanisa iipropati zemveli zokuzinzisa kunye neenzuzo ezongezelelweyo, ezifana nomsebenzi wokulwa neentsholongwane, amandla okuzicoca, okanye ukumelana ne-UV okwandisiweyo. Olu phuculo aluphuculi kuphela ukusebenza kunye nobude bephepha lodonga elinegwebu kodwa lukwavula amathuba amatsha okusetyenziswa koyilo lwangaphakathi. Ukongeza, uphuhliso lwezinto ezizinzisa ezikrelekrele ezinokuphendula kwizikhuthazo zokusingqongileyo, njengotshintsho lobushushu okanye ukufuma, lunesithembiso sokwenza izinto zephepha lodonga ezizilungelelanisayo ezinokulungisa iipropati zazo ngokuguquguqukayo ukuhlangabezana neemfuno zeendawo ezahlukeneyo.
Ukuqukumbela, izinto zokuqinisa ulwelo azikho nje kuphela kwezongezo; zezona zinto ziphambili ezenza iphepha lodonga elinogwebu lisebenze kakuhle, lithembeke, kwaye lizinze. Njengoko imfuno yezinto zoyilo lwangaphakathi ezisemgangathweni ophezulu nezinobuhlobo nokusingqongileyo iqhubeka isanda, indima yezinto zokuqinisa ulwelo iya kuba yinto ebaluleke kakhulu, iqhube ubuchule kwaye ibumbe ikamva leshishini lephepha lodonga.
