Ungazivelisa njani iiphaneli zodonga zeWPC ezikumgangatho ophezulu?

Imiba Esibhozo Ebalulekileyo Ekufuneka Iqwalaselwe KwiI-WPCImveliso

1. Ukukhethwa kunye nokuQulunqwa kwezinto eziluhlaza

• Unyango lomgubo womthi:Umthamo womswakama kufuneka ulawulwe ngokungqongqo (ngesiqhelo <2%), kwaye ukusasazwa kobukhulu bamasuntswana kufuneka kufane. Ukufuma okugqithisileyo kukhokelela ekuphukeni kwegwebu nasekuqhumeni, okuchaphazela ukugqitywa komphezulu kunye namandla.

• Izinto ezisisiseko zePlastiki:Uhlobo lwe-PVC okanye i-PE/PP kunye nomlinganiselo wezinto ezingasetyenziswanga xa zisetyenziswa kwakhona zibalulekile. Izinto ezisetyenziswa kwakhona ezigqithisileyo okanye ezikumgangatho ophantsi zichaphazela kakhulu imozulu yemveliso, amandla ayo, kunye nokuzinza kombala.

• Inkqubo yokongeza:Ibandakanya ii-agents zokudibanisa (ukuphucula i-interfacial bonding yomthi-plastiki), ii-lubricants (ezichaphazela isantya sokukhupha kunye nomgangatho womphezulu), iziqinisi (ukuthintela ukubola kobushushu kunye nokuwohloka kwe-UV), ii-agents ezikhupha amagwebu (ukulawula uxinano kunye neendleko), njl. Le fomyula yimfihlo yorhwebo ephambili kwaye ifuna umlinganiselo ochanekileyo.

2. Ukuxuba kunye nokuPelletisa

• Ukuxuba Ubunye:Izinto eziluhlaza kunye nezongezo kufuneka zisasazeke ngokulinganayo kwinqanaba le-microscopic. Ukungahambelani kakuhle kukhokelela kwiziphene zokusebenza kwindawo ethile (umz., ukutshintsha kombala, amabala aqhekekileyo, ukugoba).

• Ulawulo lobushushu beNkqubo:Amaqondo obushushu aphezulu kakhulu ngexesha lokuxuba nokufaka iipellets anokubangela ukubola kweplastiki okanye ukungasebenzi kakuhle kwezongezo, ngelixa amaqondo obushushu aphantsi kakhulu ebangela ukuxutywa okungasebenzi kakuhle.

3.Inkqubo yokubumba i-Extrusion

• Ubushushu kunye noxinzelelo:Amaqondo obushushu kwindawo nganye ye-extruder (ukondla, ukunyibilika, ukufana, ukufa) kufuneka abekwe ngokuchanekileyo. Amaqondo obushushu angalunganga akhokelela ekufakweni kakubi kweplastikhi, iindawo ezirhabaxa, kunye noxinzelelo olugqithisileyo lwangaphakathi olubangela ukuguguleka.

• Uyilo lweSikere kunye neDie:Izikrufu ezizinikeleyo kunye needayi ezichanekileyo zibalulekile ekuphumeni okuzinzileyo, kwiindawo ezithe tyaba, kunye nokuthungwa okucacileyo. Iidayi zifuna ukucocwa nokugcinwa rhoqo.

• Ukupholisa kunye nokulinganisa:Uyilo lwetanki yokulinganisa i-vacuum kunye nenkqubo yokupholisa lubalulekile. Ukupholisa okungalinganiyo okanye okunganelanga yimbangela ephambili yemvelisoukugoba kunye nokuguqulwa.

4. Unyango Lomphezulu kunye neLamination

• Ukuprinta kwi-Intanethi:Ubunzulu, ukucaca, kunye nokwenyani kobume bumisela ngokuthe ngqo umgangatho wemveliso. Ubushushu kunye noxinzelelo lwerola yokuhombisa kufuneka zihambelane nesantya sokuphuma.

• Ukucoca:Ukuguguleka kunye nokumelana ne-UV kwefilimu yokuhombisa, kunye nobushushu, uxinzelelo, kunye nolawulo loxinzelelo ngexesha lokulayita, kumisela ukuqina kunye nokunamathela komaleko wokugqibela, okuthintela ukuqhekeka okanye ukuxobuka kamva.

5. Uzinzo lweMilinganiselo kunye nokuCwangciswa emva koBuchule

• Ukusika Ubude:Ukuchaneka kokusika kuchaphazela ngqo iziphumo zokufakelwa. Iibher kunye nemiphetho eqhekekileyo ziimpawu eziqhelekileyo zemveliso ekumgangatho ophantsi.

• Unyango Lokwaluphala (Izinongo):Emva kokusikwa, iimveliso kufuneka zilale tyaba kwindawo enobushushu obungaguqukiyo kunye nomswakama kangangexesha elithile (ngesiqhelo iiyure ezingama-24-72) ukuze kukhululwe uxinzelelo lwangaphakathi. Le yinkquboinyathelo elibalulekileyoukuthintela ukuguquguquka nokuncipha emva kokufakwa, kodwa kudla ngokunganakwa ziifektri ezincinci.

6. Uhlolo loMgangatho kunye noLawulo

• Uhlolo oluqhutywa kwiNkqubo:Ubukhulu, ububanzi, uxinano, kunye nomgangatho womphezulu weemveliso ezikwi-intanethi kufuneka zithathwe iisampulu kwaye zihlolwe.

• Uvavanyo Lokusebenza:Yenza uvavanyo lwelabhoratri rhoqo kwiimveliso ezigqityiweyo ukuze ufumane izalathisi ezibalulekileyo: ukuthintela ukungenwa kwamanzi, amandla okuguquguquka, ukumelana nempembelelo, ukuguquguquka kwemozulu (ukuguga kwe-QUV), ukulinganiswa komlilo, ukukhutshwa kwe-formaldehyde, njl.

7. Indawo yokuvelisa kunye nezixhobo

• Ucoceko:Ukulawulwa kothuli olubi kwindawo yemveliso kuchaphazela ukucoceka komphezulu wemveliso kunye nomgangatho we-lamination.

• Ukugcinwa kwezixhobo:Lungisa rhoqo iinkqubo zokulawula ubushushu kunye nezikrufu kunye needayi ukuqinisekisa ukuba izixhobo zikwimeko efanelekileyo.

8. Ukupakisha kunye nokugcina impahla

• Indlela yokuPakisha:Kufuneka zipakishwe ngokuthe tyaba kwiipalethi kwaye ziqiniswe ngefilimu yokuzolula ukuze kuthintelwe umonakalo obangelwa kukutyumza nokungqubana ngexesha lokuthuthwa komgama omde.

• Indawo yokugcina impahla:Kufuneka igcinwe ngaphakathi endlwini kwindawo epholileyo neyomileyo, kuthintelwe ukukhanya kwelanga ngqo kunye nomswakama ukuthintela utshintsho olubonakalayo okanye lweekhemikhali kwiipaneli ngaphambi kokufakwa.
