Okwangoku, uninzi lweenkampani zokupakisha kwilizwe lam zisebenzisa iinkqubo ezimbini ukuvelisa iibhokisi zemibala: (1) kuqala printa iphepha elinombala, uze ugqume ifilimu okanye iglasi, uze ufake iglu ngesandla okanye udibanise ngokuzenzekelayo ubumba olugobileyo; (2) Imifanekiso enemibala kunye nemibhalo iprintwa kwifilimu yeplastiki, ize igqunywe kwikhadibhodi, ize incamathiselwe kwaye yenziwe.ibhokisi yetshokholethi yeValentine
Nokuba yeyiphi na inkqubo esetyenziswayo ukuvelisa iibhokisi zemibala yebhokisi yemibala, uxinzelelo lwayo lokuthwala kunye namandla okucinezela aphantsi kakhulu kuneebhokisi ze-watermark eziqhelekileyo zezinto ezifanayo (eziveliswe ngomgca wekhadibhodi), kwaye kunzima ukuqinisekisa umgangatho xa abathengi beswele ngokukhawuleza okanye ngeentsuku zemvula. Abavelisi abanengxaki enkulu, ngoko ke bangasombulula njani?ikhekhe letshokholethi yebhokisi
Wonke umntu uyazi ukuba iibhokisi eziveliswa ngumgca wekhadibhodi zenziwa ngokufaka iglu, ukufudumeza ukuze kuhlanganiswe ngokukhawuleza, nokomisa; ngelixa ibhokisi yebhokisi yemibala elaminethiweyo ingafudunyezwa kwaye yomiswe, kwaye ukufuma okukwiglu kungena ephepheni. Kudibene nomqobo wevarnish kumphezulu onemibala kunye nefilimu yeplastiki, ukufuma okukwibhokisi engenanto akunakuphela ixesha elide, kwaye kuya kuthamba ngokwendalo kwaye kunciphise amandla ayo. Ke ngoko, sikhangela isisombululo sengxaki kwezi zinto zilandelayo:ibhokisi yetshokholethi yesipho
⒈ ukuhlanganiswa kwephepha iibhokisi zetshokholethi zodidi
Amanye amashishini anokungaqondi kakuhle oku: okukhona ubunzima bephepha ngaphakathi bukhula, kokukhona uxinzelelo lwebhereyitha kunye namandla okuxinwa kwebhokisi kuya kwanda, kodwa oku akunjalo. Ukuze konyuswe uxinzelelo lwebhereyitha kunye namandla okuxinwa kwebhokisi yombala webhokisi yombala, amandla okuthwala uxinzelelo lwephepha eliphambili kufuneka aphuculwe. Logama nje iphepha elingaphezulu lingabonakalisi mikhondo ebotshelelweyo emva kokuncamathiselwa, iphepha elinobunzima obuphantsi kufuneka lisetyenziswe kangangoko; iphepha eliphambili kunye nephepha lethayile zezona zilungileyo. I-straw pulp okanye iphepha le-pulp yomthi enamandla amahle kunye namandla aphezulu okuxinwa kwendandatho. Musa ukusebenzisa iphepha elibotshelelweyo elinamandla aphakathi okanye aqinileyo ngokubanzi, kuba ikakhulu ngumxube we-pulp eluhlaza kunye ne-pulp ephinda isetyenziswe, enokufunxwa kwamanzi ngokukhawuleza, amandla aphantsi okuxinwa kwendandatho, kunye nokuqina okuhle kodwa ukuqina okuphantsi. Ngokovavanyo, izinga lokufunxwa kwamanzi kwephepha elibotshelelweyo elinamandla aphakathi liphezulu nge-15%-30% kunelo lephepha elibotshelelweyo elilinganiswa ngendlela yeKebo; ubunzima bephepha elingaphakathi bunokwandiswa ngokufanelekileyo. Ukuziqhelanisa kuye kwabonisa ukuba ukunciphisa igrama yephepha elingaphakathi kunye nokwandisa igrama yephepha elirhabaxa kunye nephepha eliphambili kuneenzuzo ezikhuphisanayo ngakumbi ngokubhekiselele kumgangatho kunye nexabiso.ibhokisi yesipho yetshokholethi.ibhokisi yobungakanani be-preroll king
⒉Umgangatho weglueiibhokisi zezipho zetshokholethi
Uninzi lwemveliso yeekhathoni ngoku lusebenzisa iglu yecornstarch eyenziwe ekhaya okanye ethengiweyo. Iglu yecorn esemgangathweni ophezulu ayinamandla okubopha kakuhle kuphela, kodwa inokunyusa uxinzelelo kunye nokuqina kwekhadibhodi, kwaye umzimba webhokisi akulula ukuyiguqula. Umgangatho weglu yestarch yecorn unxulumene kakhulu nenkqubo yemveliso, indawo engqongileyo, umgangatho wezinto eziluhlaza kunye nezincedisayo, kunye nexesha lokuxuba. Iimfuno zomgangatho wecornstarch, ubuncinci be-98-100 mesh, umxholo womlotha ongadluli kwi-0.1%; umxholo wamanzi yi-14.0%; i-asidi yi-20CC/100g; i-sulfur dioxide yi-0.004%; ivumba eliqhelekileyo; umbala omhlophe okanye otyheli kancinci.ibhokisi encinci yetshokholethi
Ukuba umgangatho wesitatshi esifakwe i-gelatinized awuhlangabezani nalo mgangatho, umlinganiselo wamanzi unokuncitshiswa ngokufanelekileyo ngokuxhomekeke kwimeko. Njengoko ubushushu bunyuka, umlinganiselo wamanzi kufuneka uncitshiswe ngokufanelekileyo, i-borax kunye ne-caustic soda kufuneka zonyuswe njengoko kufanelekile, kwaye ubungakanani be-hydrogen peroxide kufuneka buncitshiswe. Iglu ephekiweyo akufuneki igcinwe ixesha elide, ingakumbi ehlotyeni, kungcono ukuyisebenzisa njengoko usenza. Ukongeza i-3%-4% ye-formaldehyde, i-0.1% ye-glycerin kunye ne-0.1% ye-boric acid kwiglu kunokunyusa ukumelana kwamanzi kwephepha, kukhawulezise isantya sokubopha, kwaye komeleze ubulukhuni bekhadibhodi.ibhokisi yetshokholethi yesipho
Ukongeza, iglue yekhemikhali enobuhlobo nokusingqongileyo, oko kukuthi, iglue ye-PVA, ingasetyenziswa xa kugxunyekwa ibhodi yephepha. Iimpawu zayo zezokuba ikhadibhodi erhabaxa elaminethiweyo ithe tyaba, ithe tye, inamathele kakuhle, kwaye ihlala ixesha elide ngaphandle kokuguquka. Indlela yokuvelisa yile (ukuthatha i-100kg yeglue njengomzekelo): umlinganiselo wezinto: i-polyvinyl alcohol 13.7kg, i-polyvinyl acetate emulsion 2.74kg, i-oxalic acid 1.37kg, amanzi 82kg, umlinganiselo wamanzi 1:6). Okokuqala, fudumeza amanzi ukuya kuma-90°C, yongeza i-polyethylene glycol kwaye uvuselele ngokulinganayo, qhubeka ufudumeza de amanzi abile, gcina ushushu iiyure ezi-3, emva koko yongeza i-oxalic acid kwaye uvuselele, ekugqibeleni yongeza i-polyvinyl acetate emulsion kwaye uvuselele ngokulinganayo.
⒊Ubungakanani beglu
Nokuba kukufakelwa kweglue ngesandla okanye ngokuzenzekelayo kwiindawo ezinemibala, ubungakanani beglue esetyenziswayo akufuneki bube bukhulu kakhulu. Kwimveliso yokwenyani, abanye abasebenzi bayandisa ngobuqhetseba ubungakanani beglue esetyenziswayo ukuze baphephe ukususa iglue, nto leyo engacebisekiyo kwaye kufuneka ilawulwe ngokungqongqo. Ubungakanani beglue esetyenziswayo kufuneka bube yi-80-110g/m2. Nangona kunjalo, kuxhomekeke kubukhulu beglue edityanisiweyo, kuyacetyiswa ukuba ubambe ubungakanani beglue kwaye ugqume ngokulinganayo iincopho zeglue. Ukuba nje akukho glue edityanisiweyo, kokukhona iglue incinci, kokukhona ingcono.ikesi yecuba eqhelekileyo
⒋Umgangatho wekhadibhodi ecala linyeukuhanjiswa kwebhokisi yetshokholethi
Umgangatho wekhadibhodi erhabaxa enecala elinye umiselwa ngumgangatho wephepha elisisiseko, uhlobo lwe-corrugation, ubushushu bokusebenza bomatshini we-corrugating, umgangatho we-adhesive, isantya sokusebenza komatshini, kunye nenqanaba lobuchwephesha lomqhubi.
