Indlela yokukhetha i-zipper esemgangathweni ophezulu

I-zipper, eyona nto inkulu kakhulu yekhulu lama-21, ngoku kulula ukungayinaki ukubaluleka kwayo, kuba iye yaba zixhobo eziqhelekileyo, kodwa umgangatho wokuthengwa kwayo awukwazi ukuhoywa.Isiqwenga sempahla sinokuba nempembelelo ebalulekileyo ngenxa yomgangatho we-zipper.Imigangatho yomgangatho wayo yaziswa ngolu hlobo lulandelayo:

Indlela yokukhetha i-zipper esemgangathweni ophezulu

1. ngokwemigangatho yomgangatho we-zipper yaseYurophu, i-handbag zipper ifuna i-non-toxic, akukho azo, akukho nickel, akukho formaldehyde, inaliti yokuhlola iyadingeka, xa iyala ukuba ibekwe phambili ngokwahlukileyo.

2. Ukuba umbala uziphu umhlophe (Umbala oGqibileyo no. J-D030), uzive uthambile, ugudile, uthambile, uqinile kwaye unxibe kakuhle, amazinyo: umphezulu wamazinyo entloko kufuneka ugudiswe nomgangatho olungileyo, uzive uthambile kwaye ugudile xa iyatsalwa, kwaye ingxolo iyancipha, kwaye amazinyo akufanele abe mnyama okanye abe tyheli.

3. Ibhanti lelaphu leziphu elikwisiphelo esiphezulu kufuneka libe yiyunifomu, lingabi nabala, lingabikho libala, lizive lithambile;Umkhombandlela othe nkqo okanye othe tye, ilaphu kufuneka libe ngamaza alinganayo kancinane okanye kungabikho maza;Ncamathelisa ilaphu kufutshane nebhanti lelaphu, kungekho lula ukuliqhawula.

4. Ukukhawuleza kombala kwi-friction: Ukukhawuleza kombala webhanti ye-zipper kuya kuhlangabezana neemfuno ze-GB251 emva kovavanyo lwe-friction.Ukukhawuleza kombala ekuhlambeni: ukukhawuleza kombala webhanti yekhonkco emva kokuhlamba kuhambelana nebakala 3-4 elichazwe yi-GB250.

5. amazinyo e-zipper chain ahlelwe kakuhle, akukho mazinyo alahlekileyo, amazinyo amabi;

6. nganye iimitha ezingama-4000 zobunzima kufuneka ingabi ngaphantsi kwe-40KG, ibhanti lelaphu leziphu akufanele liqulathe i-agent fluorescent.

7. Umahluko wombala webhanti yekhonkco kwibhetshi efanayo uya kufikelela kwinqanaba le-3 elichazwe kwi-GB250.

8. ngokomgangatho wesizwe, amandla okutsala i-zipper ≥340N;Tsala kwaye uvale kakuhle ≤5N.
