Nyamuneka ntimugahitemo amapaleti ya pulasitiki mu buryo buhumyi. Mbere na mbere, paleti ya pulasitiki tugomba gusobanukirwa ko ari ikibaho gusa cyo gupfunyika. None se kuki duhitamo amapaleti ya pulasitiki? Mbere na mbere, tugomba gusobanukirwa ibikoresho amapaleti ya pulasitiki akozwemo, ni izihe nyubako, amoko angahe, n'inyungu zayo ni izihe?
Hari ubwoko bwinshi bw'udupira twa pulasitiki, twitwa mu buryo butandukanye muri buri gace. Mu turere tumwe na tumwe, twitwa udupira twa pulasitiki, udupira twa pulasitiki, udupira twa injection molding, udupira twa pulasitiki, udupira twa pulasitiki, udupira twa shelfu n'ibindi. Ibikoresho fatizo bya pulasitiki bikozwe muri PE na PP, ni ukuvuga thermoplastic nka polyethylene HDPE, polypropylene PP plastic, hamwe n'ibindi bikoresho byo kunoza imikorere, bigatunganywa hakoreshejwe injection molding, blow molding n'ibindi bikorwa.
Uko ibihe byagiye bihinduka, ibisabwa ku mikorere, imiterere y'ububiko, kugenzura ibikorwa no gucunga ubuziranenge byakomeje kunozwa. Bikoreshwa cyane mu bubiko, mu bikoresho, mu maduka manini, mu gutwara imizigo no mu zindi nganda. Palasitike ya pulasitiki ifite ubuziranenge bwiza, isuku kandi isukuye, kandi yoroshye kuyimesa no kuyica udukoko. Ifite imiterere yoroheje, nta mitsi ihinduka, aside na alkali birwanya, kandi nta mildew ikoreshwa. Igihe cyayo cyo gukora ni inshuro 5-7 ugereranyije n'igihe palasitike z'ibiti. Byongeye kandi, palasitike za pulasitiki zujuje ibisabwa mu kurengera ibidukikije, kandi imyanda y'ibikoresho bya palasitike ishobora kongera gukoreshwa. Nubwo igiciro cya palasitike za pulasitiki kiri hejuru, ikiguzi cyo gukoresha kiri hasi ugereranyije n'igihe palasitike z'ibiti.
Hari ingano nyinshi z'ibicuruzwa, ingano zisanzwe ni: 1200*1000, 1100*1100, 1200*1200, 1200*1100, 1300*1100, 1200*800, 1400*1100, 1400*1200, 1400*1400, 1500*1500, n'ibindi.
Mu guhitamo pallet za pulasitiki, ubu hariho ibyiciro bibiri gusa hakurikijwe imiterere:
Imwe ni ubwoko bw'uruhande rumwe, ipaleti ya pulasitiki ifite uruhande rumwe ishobora gukoreshwa ku ruhande rumwe gusa;
Iya kabiri ni ubwoko bw'impande ebyiri kandi ishobora gukoreshwa ku mpande zombi;
Amahitamo y'amapaleti ya pulasitiki afite impande imwe cyangwa amapaleti ya pulasitiki afite impande ebyiri agomba kugenwa hakurikijwe ibikoresho byo kubika, gupakira no gupakurura hamwe n'imiterere yabyo (nk'ubwoko bw'ububiko, ubwoko bw'ububiko, aho gushyira ibintu mu buryo cyangwa aho bishyirwa, n'ibindi).
1. Hanyuma ubwoko bw'uruhande rumwe bugabanyijemo: 1. Ubwoko bw'ikoreshwa ry'uruhande rumwe; 2. Ubwoko bw'urukuta rurerure rwa metero icyenda; 3. Ubwoko bw'urukuta rurerure rwa metero icyenda; 4. Ubwoko bw'urukuta rurerure; 5. Ubwoko bw'urukuta rurerure; 6. Urukuta rurerure rwa metero ebyiri. 7. Inyuguti ya Flat Chuan; 8. Agapapuro ka pulasitiki k'urukuta rurerure.
Icya kabiri, ubwoko bw'impande ebyiri bugabanyijemo: ubwoko bw'impande ebyiri burambuye; ubwoko bw'urusobe rw'impande ebyiri.
Dukurikije icyo ikoreshwa, hari ubwoko butatu: 1. Ubwoko bw'ameza; 2. Ubwoko busanzwe; 3. Palasitike yoroheje ya pulasitiki.
Hari ubwoko bubiri hakurikijwe inzira:
1. Palati yo gushushanya: Ubwoko bw'ibumba rya pulasitiki ni bwo bwoko bunini bwa palati za pulasitiki zikorerwa mu Bushinwa. Ubushinwa bwazanye ibikoresho byo mu mahanga byo gukora ikoranabuhanga ryo gushushanya ibumba kuva mu myaka ya 1980, ariko isoko ntirirafungurwa bitewe n'impamvu zitandukanye nko ku giciro. Byashyizeho uburyo bwo kwagura umusaruro wa palati za pulasitiki zikoreshwa mu nganda.
2. Palati yo gushushanya: Bitewe n'igiciro n'imiterere y'imikorere, hari inganda nke cyane mu Bushinwa zikoresha uburyo bwo gushushanya kugira ngo zikore palati za pulasitiki. Zikozwe mu bunini bwa molekuli ifite uburemere bwinshi bwa poly (HWMHDPE), zishobora gukoreshwa mu buryo bwa tekiniki n'ubwo gukoresha intoki, kandi palati ifite impande ebyiri ishobora gukoreshwa ku mpande zombi, bigatuma ubuzima bwo gukora burushaho kuba bwiza. Bitewe n'igiciro kinini cy'ibikoresho fatizo bya pulasitiki byatoranijwe kuri iyi palati ikomeye cyane, ingorane mu buryo bwo kuyitunganya ni nyinshi cyane, kandi ubuzima bwo gukora ibicuruzwa ni burebure cyane, bushobora kugera ku myaka 5 kugeza ku 10. Birumvikana ko igiciro kizaba kinini ku kugura rimwe, ariko ikiguzi cyuzuye cyo kuyikoresha kiba kiri hasi. Iyo hakenewe gukoreshwa imbaraga nyinshi, iyi palati ikomeye cyane ishobora gutoranywa.
Dukurikije aho ikoreshwa, igabanyijemo: 1. Ubwoko bw'ihindagurika ry'ubutaka, n'ubutaka bwitwa igikorwa; 2. Ubwoko bw'ishyirwa ry'ubutaka (ubwoko bw'ishyirwa ry'ubutaka); 3. Byoroshye; 4. Biremereye; 5. Amapaleti ya pulasitiki ashobora gukoreshwa.
Kugira ngo dusobanukirwe ibisobanuro by'umutwaro uhindagurika n'umutwaro uhoraho: umutwaro uhoraho bivuga uburemere ntarengwa ipallet ishobora gutwara mu gihe cyo kugenda iyo ikoreshejwe na forklift cyangwa hydraulic pallet truck (ifite curvature iri munsi ya 1.5% ni ibisanzwe). Umutwaro uhoraho uvuga uburemere ntarengwa ipallet ya pulasitiki yo hasi ishobora gutwara mu gupakira. Byongeye kandi: umutwaro uhoraho uvuga uburemere ntarengwa ipallet ya pulasitiki ifite imizigo ishobora gutwara iyo ishyizwe ku gipakira (urugero rwo gupfunyika ruri muri 1% ni ibisanzwe). Muri rusange, ipallet zisanzwe zishobora gutwara 0.4T ~ 0.6T iyo ipallet ishyizwemo imizigo, naho ipallet ziremereye zishobora gutwara 0.7T ~ 1T.
Uburyo bwo gukoresha palati za pulasitiki burimo: guhindura ubutaka, gukoresha palati, gukoresha palati, nibindi. Uburyo butandukanye bwo gukoresha busaba guhitamo ubwoko bwa palati za pulasitiki zikwiye. Niba ari uguhindura ubutaka, atari ku gipangu, atari ugushyiraho, amahitamo ya mbere: metero icyenda, Sichuan, Tian, niba ari ku gipangu, amahitamo ya mbere: Sichuan (umuyoboro w'icyuma uhitamo), niba ari ugushyiraho, amahitamo ya mbere: Palati za pulasitiki zifite impande ebyiri.
Uko ibintu bigenda bizamuka buhoro buhoro uko ibihe bigenda bisimburana, ibisabwa mu gupakira no gutwara ibintu nabyo biragenda birushaho kwiyongera. Kugura amapaleti ya pulasitiki no gukoresha ibikoresho byo gupakira imbere hamwe n'ibisabwa mu gutwara ibintu ntabwo byatandukanijwe mu nzego nyinshi. Muri make, nubwo amapaleti ya pulasitiki ari ku isoko ryose kandi ni yo agize uruhare runini mu ikoreshwa, ariko ikoreshwa ry'amapaleti ya pulasitiki ni igice cy'ingenzi cy'isoko ryose. Ikibazo kigomba kwitabwaho ni uguhitamo ibikoresho n'imiterere ikwiye hakurikijwe imiterere yihariye y'ibicuruzwa.
