Ukufezekisa iziphumo zonyango ezifanelekileyo, kwizinto ezininzi kufuneka ziqwalaselwe, kubandakanya:
I-1. Imo yegumbi lokuphilisa kunye nemeko efanelekileyo: isantya kunye nexabiso lomoya oshushu ovela kwisixhobo sokufudumeza kunye netonela; umhlaba kunye namacala amabini okanye amaqela egumbi lokuphilisa ane-moya eyaneleyo kwaye ifanayo nomoya ovuthayo. umahluko omncinci phakathi kweqondo lokwenyani kunye nokuseta ubushushu, kunye nokugcinwa kobushushu kunye nokukhutshelwa kwenkunkuma kuyahlangabezana nezicelo; I-roll yefilimu kulula ukuyihambisa kwaye ithathe.
2. Iimveliso zihlangabezana nezicelo zobugcisa.
3. Imisebenzi, ixabiso le-corona, ukumelana nobushushu, njl. Njl.
I-4. Ababukeli: I-Sonvent Abenoive, imbeketive engenabuhle, i-onvere okanye i-onveren okanye i-tople facker andhed, inyibilike, inyibilike, njl.
Eli phepha ligxile kwiifilimu zelebhusayithi kunye nemikhono.
I-1. Iifilimu zemibala
Ukuchasana komzimba, ubushushu kunye nokusebenza kwesithintelo kwefilimu ye-PE, esetyenziswe ngokubanzi, kuya kuba ngcono, xa uxinzelelo lwe-pen liphuma. Iifilimu ze-PE ezine-inzuzo efanayo kodwa iinkqubo ezahlukeneyo zokuvelisa zinemisebenzi eyahlukileyo.
I-CPE inokuthotyelwa ngokukhawuleza, nge-crystallity ephantsi, engafihlisiyo kunye ne-turbidity ephantsi. Kodwa ilungiselelo lemolecular alikho ngokungaqhelekanga, lenza ukuba kubekho umsebenzi ombi oqhelekileyo, owosulelayo. Kwaye iyafana ne-ldpe. Ke ngoko, ukunyanga amaqondo obushushu akufanele ukuphakama kakhulu xa usebenzisa iifilimu ze-PE. Xa ukumelana kobushushu kuPhuculo, iqondo lokunyanga linokuphakama.
I-2. Ababukeli
2.1 EI-CEPLUkusekwe
Ngokwemisebenzi yeefilimu zelebhulethi kunye neencwadana, iimeko zokunyanga zinokwahlulwa zibe ngamanqanaba ahlukeneyo:
1. Ubushushu 35℃, ixesha lama-24-48h
2. Ubushushu obuyi-35-40℃, ixesha lama-24-48h
3. Ubushushu 42-45℃, ixesha 48-72h
4. Ubushushu 45-55℃, IXESHA 48-96H
I-5. Iqondo elikhethekileyo, lobushushu ngaphezulu kwe-100℃, ixesha ngokwenkxaso yezobugcisa.
Kwiimveliso eziqhelekileyo, ukuqwalasela ububi, ubukhulu, ibhlokhi, ukuxhathisa ubushushu beefilimu kunye nobungakanani beengxowa, ukunyanga ubushushu akufuneki kube kuphakama kakhulu. Ngokwesiqhelo, i-42-45℃okanye ngezantsi kwanele, ixesha lama-48 ukuya 72.
Iifilimu zangaphandle zelebhule, ezifuna ukuba intsebenzo ephakamileyo kunye nokuxhathisa ubushushu obuhle zilungele ukunyangwa okuphezulu, njengama-50℃. Iifilimu zangaphakathi, njenge-PE okanye i-chere yokutsala i-CPP, ilungele i-42-45℃, Ixesha lokunyanga kunokuba ixesha elide.
Ukubilisa okanye ukuphendula iimveliso, ezifuna ukuSebenza okuphezulu kunye nokuxhathisa ubushushu, kufuneka zikhuphele ingqalelo kwiimeko ezibonelela ngefeksti.
Ixesha lokunyanga kufanele ukuba likhuphe ireyithi yokugqitywa kwamandla, ukulungelelaniswa kwengqumbo kunye nokusebenza kobushushu.
Iimveliso ezizodwa zinokufuna ubushushu obuphezulu.
2.2 Ukunamathela kweSolventi
Ukuba ukusebenza kwendlela yokutywina kuhlangabezana nemfuno, kuba iimveliso ezisasazayo zeSolvential, apho iifilimu zangaphakathi zinoxinano olusezantsi, iincwadana ezinemingxunya baneempawu ezininzi zasimahla, zenza kube nzima ukutywina. Ke ngoko, ukunyangwa amaqondo obushushu asezantsi kuyacetyiswa, nge-38-40℃.
Ukuba inqanaba lokuphendula lokuphendula liyahlangabezana nemfuno, ixesha elide lokunyanga kufuneka liqwalaselwe.
Ukuba ubushushu bokutsalwa kweefilimu zinoxinano oluphezulu, iqondo lokunyanga i-40-45℃. Ukuba ireyithi yokugqitywa kwempendulo kunye nendlela yokutywinwa kwengqondo kufuneka iphucule, ixesha lokunyanga lixesha elide.
Uvavanyo ngokungqongqo kuxa kufuneka ngaphambi kokuba kuveliswe ubunzima, ukuqinisekisa umgangatho.
Yintoni engaphezulu, umswakama kufuneka uqwalaselwe. Ngakumbi kubusika owomileyo, umswakama ofanelekileyo unokukhawulezisa umgangatho wokuphendula.
2.3 Ababhambisi bamanzi asekwe
Xa ivumba i-vcpp, umatshini wokuwile kufuneka wome ngokwaneleyo, okanye ungqimba lo walala uya kuba oxidid. Ngexesha lokunyanga, iqondo lobushushu alifanele liphezulu kakhulu okanye liphantsi kakhulu. Iqondo lokushisa eliphezulu liya kukhokelela kwi-coultion ephezulu.
2.4 inyibilikisile
Ngokwesiqhelo khetha unyango lwendalo, kodwa indlela yokubulala i-adhesions emva kokunyibilika kufuneka iqatshelwe.
I-3. Ukulawula ngokungqongqo
Ngokutsho kophando, kumcimbi wokuphendula, akukho phantse akukho mpendulo iphantsi kwe-30℃. Ngaphezulu kwama-30℃, yonke i-10℃Iphezulu, umlinganiso wokuphendula uphucula amaxesha ama-4. Kodwa yona'Ayilunganga ukuphucula amaqondo obushushu ukuze akhawuleze amanqanaba okuphendula ngokungasebenzi kakuhle, izinto ezininzi kufuneka ziqatshelwe:Okwenziweyo Inqanaba lokuphendula, i-coultions and kunye ne-sub yokutywitha.
Ukufezekisa esona siphumo sobunyameko
Kuba iingxaki ezikhoyo, eziqhelekileyo zingezantsi:
Iqondo elinye, ukunyanga iqondo lobushushu liphantsi kakhulu, lisenza izinga lokuphendula eliphantsi, kwaye imveliso ineengxaki emva kokuba itywiniwe okanye ibilisiwe.
Iiqondo ezimbini, iqondo lokunyanga ezimbini liphezulu kakhulu kwaye ifilimu eshushu eshushu inoxinano olusezantsi. Imveliso ineentsebenzo ezishushu ezishushu, i-factions ephezulu yokusebenza kunye neziphumo ezimbi zebhlokhi.
4. Ukuqukumbela
Ukufezekisa esona siphumo solangazelelo lulungileyo, ukunyanga ubushushu kunye nexesha kufuneka kuthathwe isigqibo malunga nendawo yokushisa esingqongileyo kunye nokufuma, ukusebenza kwefilimu kunye nokusebenza okunembeko.
