Okwangoku, iinkampani ezininzi zokupakisha kwilizwe lam zisebenzisa iinkqubo ezimbini ukuvelisa iibhokisi zemibala: (1) okokuqala printa iphepha elingaphezulu elinombala, emva koko ligqume ifilimu okanye i-glazing, kwaye emva koko lifake ngesandla iglu okanye ngomatshini ngokuzenzekelayo ukugcoba ukubunjwa kwamazinki; (2) Imifanekiso enemibala nemibhalo iprintwa kwifilimu yeplastiki, ize igqunywe kwikhadibhodi, ize incamatheliswe ize yenziwe.ibhokisi yetshokolethi kavalentine
Nokuba yeyiphi na inkqubo esetyenziselwa ukuvelisa iibhokisi zemibala yebhokisi yemibala, uxinzelelo lwayo kunye namandla oxinzelelo asezantsi kakhulu kuneebhokisi ze-watermark eziqhelekileyo zezinto ezifanayo (eziveliswe ngumgca wekhadibhodi), kwaye kunzima ukuqinisekisa umgangatho xa abathengi bengxamisekile. imfuno okanye ngeentsuku zemvula. Abavelisi abaneengxaki ezinzulu, ngoko bayisombulula njani?ibhokisi ikeyiki itshokolethi
Wonke umntu uyazi ukuba iibhokisi eziveliswa ngumgca wekhadibhodi zenziwe ngokufaka iglue, ukufudumeza ukudibanisa ngokukhawuleza, kunye nokumisa; ngelixa ibhokisi yombala webhokisi yombala we-laminated yekhadibhodi ayitshisi kwaye yomiswe, kwaye ukufuma kwiglue kungene kwiphepha. Ngokudibanisa nomqobo we-varnish ebusweni obunemibala kunye nefilimu yeplastiki, umswakama kwibhokisi engenanto ayinakuchithwa ixesha elide, kwaye ngokwemvelo iya kuthobisa kwaye inciphise amandla ayo. Ke ngoko, sijonga isisombululo kule ngxaki kwezi zinto zilandelayo:ibhokisi itshokolethi isipho
⒈ ukuhanjiswa kwephepha iibhokisi itshokolethi obutofotofo
Amanye amashishini anokungaqondi kakuhle okunjalo: ubunzima obukhulu bephepha ngaphakathi, ngakumbi ukunyanzeliswa koxinzelelo kunye namandla okunyamezela kwebhokisi kuya kwandiswa, kodwa oku akunjalo. Ukuze kuphuculwe ukunyanzeliswa koxinzelelo kunye namandla acinezelayo kwibhokisi yombala webhokisi yombala, amandla okuthwala uxinzelelo lwephepha eliphambili kufuneka aphuculwe. Lo gama nje iphepha elingaphezulu lingabonakalisi i-corrugated traces emva kokuba iglue, iphepha elinobunzima obuphantsi kufuneka lisetyenziswe kangangoko kunokwenzeka; Iphepha eliphambili kunye nephepha lethayile lisetyenziswa kakuhle. I-pulp ye-Straw okanye iphepha le-pulp yeplanga elinamandla alungileyo kunye namandla aphezulu oxinzelelo lweringi. Musa ukusebenzisa amacangci aphakathi okanye amandla ngokubanzi, kuba ubukhulu becala ngumxube wepulp ekrwada kunye nepulp ehlaziyiweyo, enokufunxeka ngokukhawuleza kwamanzi, amandla okucinezela iringi ephantsi, kunye nokuqina okuhle kodwa ukuqina okuphantsi. Ngokovavanyo, isantya sokufunxa amanzi sephepha le-corrugated eliphakathi kwe-15% -30% ephezulu kunelo liphepha le-pulped elilinganiswe yindlela ye-Kebo; ubunzima bephepha le-lining linganyuswa ngokufanelekileyo. Ukuziqhelanisa kuye kwabonisa ukuba ukunciphisa igrama yephepha langaphakathi kunye nokunyusa igrama yephepha le-corrugated paper kunye ne-core paper inenzuzo yokukhuphisana ngakumbi kumgangatho kunye nexabiso.ibhokisi yesipho yeetshokholethi.preroll ukumkani ubungakanani ibhokisi
⒉Umgangatho wegluIibhokisi zesipho zetshokholethi
Uninzi lwemveliso yebhokisi ngoku isebenzisa iglue eyenziwe ekhaya okanye ethengiweyo ye-cornstarch. Iglu ekumgangatho ophezulu weglue ayinayo kuphela amandla okudibanisa okulungileyo, kodwa inokwandisa uxinzelelo kunye nokuqina kwekhadibhodi, kwaye umzimba webhokisi awukho lula ukukhubazeka. Umgangatho weglue wesitashi sengqolowa uhambelana ngokusondeleyo nenkqubo yokuvelisa, indawo engqongileyo, umgangatho wezinto ezikrwada kunye nezincedisayo, kunye nexesha lokuxuba. Iimfuno zomgangatho we-cornstarch, i-fineness 98-100 mesh, umxholo womlotha ongadluli kwi-0.1%; umthamo wamanzi 14.0%; ubumuncu 20CC/100g; sulfur dioxide 0.004%; ivumba eliqhelekileyo; mhlophe okanye tyheli kancinci ngombala.ibhokisi encinci yetshokolethi
Ukuba umgangatho we-gelatinized starch awuhambisani nalo mgangatho, umlinganiselo wamanzi unokuncitshiswa ngokufanelekileyo ngokuxhomekeke kwimeko. Njengoko izinga lokushisa liphakama, umlinganiselo wamanzi kufuneka uncitshiswe ngokufanelekileyo, i-borax kunye ne-caustic soda kufuneka inyuswe ngokufanelekileyo, kwaye inani le-hydrogen peroxide kufuneka lincitshiswe. Iglue ephekiweyo ayifanele igcinwe ixesha elide, ngakumbi ehlobo, kukulungele ukuyisebenzisa njengoko uyenzayo. Ukongeza i-3% -4% ye-formaldehyde, i-0.1% ye-glycerin kunye ne-0.1% ye-boric acid kwi-glue inokunyusa ukuchasana kwamanzi ephepheni, isantya sokudibanisa, kunye nokuqinisa ikhadibhodi. ubulukhuni.ibhokisi itshokolethi isipho
Ukongeza, iglue yemichiza ehambelana nokusingqongileyo, oko kukuthi, i-PVA yokuncamathelisa, ingasetyenziselwa xa ubeka ibhodi yephepha. Iimpawu zayo kukuba i-laminated cardboard corrugated cardboard i-flat, iqondile, idibene kakuhle, kwaye ihlala ihleli ngaphandle kokuguqulwa. Indlela yokuvelisa (ukuthatha i-100kg ye-adhesive njengomzekelo): umlinganiselo wezinto eziphathekayo: i-polyvinyl alcohol 13.7kg, i-polyvinyl acetate emulsion 2.74kg, i-oxalic acid 1.37kg, amanzi angama-82kg, umlinganiselo wamanzi 1: 6). Okokuqala, fudumeza amanzi ukuya kwi-90 ° C, yongeza i-polyethylene glycol kwaye udibanise ngokulinganayo, qhubeka ushushu kuze kube yilapho amanzi abilayo, gcina ukufudumala kweeyure ezi-3, uze ungeze i-oxalic acid kwaye ugxobhoze, ekugqibeleni ungeze i-polyvinyl acetate emulsion kwaye udibanise ngokulinganayo.
⒊ Isixa seglu
Kungakhathaliseki ukuba i-manual okanye i-automatic mechanical mounting yeendawo ezinemibala, isixa seglue esisetyenzisiweyo akufanele sibe sikhulu kakhulu. Kwimveliso yokwenyani, abanye abasebenzi banyusa ngokwenziwa isixa seglue esisetyenzisiweyo ukuze kugwenywe i-degumming, engacebisekanga kwaye kufuneka ilawulwe ngokungqongqo. Isixa seglue esisetyenzisiweyo kufuneka sibe yi-80-110g / m2. Nangona kunjalo, kuxhomekeke kubukhulu be-corrugated corrugated, kuyacetyiswa ukuba ubambe ubuninzi beglue kwaye udibanise ngokulinganayo iincopho ze-corrugated. Ngethuba nje kungekho degumming, ngaphantsi kwexabiso leglue, kungcono.ibhokisi yecuba eqhelekileyo
⒋Umgangatho wekhadibhodi enecala elinyeukuhanjiswa kwebhokisi yetshokolethi
Umgangatho wekhadibhodi enecala elinye ithathwa ngumgangatho wephepha lesiseko, uhlobo lwe-corrugation, ubushushu obusebenzayo bomatshini wokutya, umgangatho wokuncamathelisa, isantya sokubaleka somatshini, kunye nenqanaba lobugcisa lomatshini. umsebenzisi.
