IiCasters zifana “nezihlangu” zefenitshala okanye izixhobo, ngoko ke ukukhetha izinto ezifanelekileyo kwenza kube lula ukuzihambisa nokukhusela umhlaba. Ngezantsi, siza kuthatha imizuzu emi-3 ukukufundisa indlela yokwahlula iingenelo kunye nokungalungi kwezinto ezintathu eziphambili ze-nylon, i-polyurethane, kunye nerabha, ukuze sinike iingcebiso zokuthenga ezisekelwe kumhlaba.
1. Isishwankathelo seMpahla
1). Inayiloni (PA)
• Amagama angundoqo: Unzima, Unzima, Unomsindo
• Iimpawu: Ubunzima obuphezulu, amandla amahle okuthwala umthwalo, kodwa ingxolo enkulu yokuqengqeleka; ayigugi kodwa ayithambeki. Emva kokuyityhala nokuyitsala ixesha elide isenokukrwela umgangatho womthi okanye iindawo zeseramikhi.
• Umzekeliso obonakalayo: Njengamatayara emoto engekho endleleni, inokuthwala imithwalo enzima kodwa igqume kakhulu.
2). I-Polyurethane (PU)
• Amagama angundoqo: Ethambileyo, Ezolileyo, Eguquguqukayo
• Iimpawu: Ukuqina phakathi kweplastiki nerabha, ingxolo ephantsi, ayixhathisi ioyile kunye ne-hydrolysis. Ifanelekile kwiindawo zokusebenzela ezingenathuli, iilebhu, izibhedlele, nakwezinye iindawo ezineemfuno ezingqongqo; ayishiyi zimpawu zimnyama phantsi.
• Umzekeliso obonakalayo: Njengesigqubuthelo esiphakathi seebhulukhwe, sizinzile kwaye sizolile.
3). Irabha (NR/SBR)
• Amagama angundoqo: Ithambile, Ibambeka, Ifikelelekayo
• Iimpawu: Ayityibiliki ngokwendalo xa ixina imithwalo enzima; ayityibiliki xa ityhala imithwalo enzima; iyafunxa uloyiko, izolile kwaye ingabizi kakhulu. Iingxaki ziquka ukuguga xa utshiswa lilanga ixesha elide kunye nokuguquguquka xa uthwele imithwalo enzima.
• Umzekeliso obonakalayo: Njengamatayara angathethiyo emoto yosapho, ifuna ukutyhalwa “buthule” kwaye iphephe ukuxinwa ixesha elide.
2. Qonda indlela yokukhetha ngetafile enye
| Iimfuno zeMeko | Izinto ezicetyiswayo | Isizathu |
| Imithwalo enzima yefektri, umgangatho wesamente | Inayiloni | Ithwala umthwalo oqinileyo, imelana nokukrweleka phantsi |
| Izibhedlele, iilebhu, iipaseji zeehotele | I-Polyurethane | Ukhuseleko oluzolileyo + umgangatho + ukumelana nokugqwala |
| Iikhabhathi zokugcina izinto zasekhaya, iikhabhathi ze-ofisi | Irabha | Ithule, ayityibiliki, ayonakalisi umgangatho womthi, ixabisa kancinci |
| ilanga elingaphandle kunye nokuchatshazelwa yimvula | I-Polyurethane (imelana ne-UV eguquliweyo) | Imelana nokwaluphala, irabha iyaqhekeka lula phantsi kwelanga |
| Ifuna indawo yokubeka iibhuleki | Nasiphi na isixhobo, gxila kwisakhiwo sebhuleki | Ubomi bephedi yebhuleki bubaluleke ngakumbi kunezinto ezisetyenziswa kumphezulu wevili |
3. Ukuthenga nge-Mnemonic ngamanyathelo amathathu
1. Jonga umgangatho: Kwimigangatho yomthi kunye neeseramikhi, ungakhetha i-PU okanye irabha; kwimigangatho yesamente okanye yentsimbi, i-nylon ifanelekile.
2. Mamela imeko-bume: Kwiiofisi nakwizibhedlele ezifuna “ingxolo engekhoyo”, kufuneka ziphephe i-nylon.
3. Linganisa umthwalo: Umthamo womthwalo we-caster enye ≥ (ubunzima bezixhobo zizonke ÷ 3), ushiya umda wokhuseleko owaneleyo.
Isishwankathelo kwisivakalisi esinye
Imithwalo enzima engenaxhala lengxolo—khetha i-nylon; ufuna ukuzola nokucoceka—khetha i-polyurethane; ufuna ukonga imali kodwa uthule—khetha irabha. Xhathisa izinto ezisetyenzisiweyo nemeko, kwaye ii-casters azisayi kuba lukhetho olunzima.
