Ungakhetha kanjani uziphu wekhwalithi ephezulu

I-zipper, ukusungulwa okukhulu kwekhulu lama-21, manje kulula ukungazinaki ukubaluleka kwayo, ngoba isiye yaba izesekeli ezivame kakhulu, kodwa ikhwalithi yokuthengwa kwayo ayikwazi ukunakwa.Isiqephu sezingubo singaba nomthelela omkhulu ngenxa yekhwalithi ye-zipper.Izindinganiso zayo zekhwalithi zethulwa kanje:

Ungakhetha kanjani uziphu wekhwalithi ephezulu

1. ngokwezinga lekhwalithi ye-ziphu yaseYurophu, izidingo ze-zipper zesikhwama ezingenabuthi, akukho azo, akukho nickel, akukho formaldehyde, inaliti yokuhlola iyadingeka, lapho iyala ukuthi ibekwe phambili ngokuhlukana.

2. Uma umbala uziphu umhlophe (Swell color no. J-D030), uzizwe uthambile, ushelela, uyisicaba, uqinile futhi uxhumeke kahle, amazinyo: ubuso bamazinyo ekhanda leziphu kufanele bushelelezi ngekhwalithi enhle, buzizwe buthambile futhi bushelelezi uma liyadonswa, futhi umsindo uyancipha, futhi amazinyo akufanele abe mnyama noma aphuzi.

3. ukudaya kwebhande leziphuphu elisezingeni eliphezulu kufanele kube iyunifomu, kungabi nabala, kungabi nesibazi, futhi kuzwakale kuthambile;Isiqondiso esiqondile noma esivundlile, indwangu kufanele ibe igagasi elifanayo kancane noma ingabi namagagasi;Namathisela indwangu eduze kwebhande lendwangu, akulula ukugqashuka.

4. Ukushesha kombala ukungqubuzana: Ukushesha kombala kwebhande uziphu kuzohlangabezana nezimfuneko ze-GB251 ngemva kokuhlolwa kokungqubuzana.Ukushesha kombala ekuwashweni: ukushesha kombala kwebhande leketango ngemva kokuwashwa kuhambisana nebanga lesi-3-4 elishiwo ngu-GB250.

5. Amazinyo eketango uziphu ahlelwe kahle, awekho amazinyo angekho, amazinyo amabi;

6. Isisindo samayadi angu-4000 ngasinye akumele sibe ngaphansi kuka-40KG, ibhande lendwangu uziphu akufanele libe ne-agent ye-fluorescent.

7. Umehluko wombala webhande leketango eqeqebeni elifanayo uzofinyelela kuleveli 3 eshiwo ku-GB250.

8. ngokwezinga likazwelonke, amandla okudonsa uziphu ≥340N;Donsa futhi uvale kahle ≤5N.
