Kuwunika kwa Miyezo Yogwiritsiridwa Ntchito Zosindikizira Zomangamanga

Zosindikizira zamapangidwe ndi zida zofunika kwambiri zolumikizira ndikusindikiza munyumba, milatho, ndi ntchito zina. Kuchita kwawo kumakhudza mwachindunji chitetezo ndi kulimba kwake. Kuwonetsetsa kuti malonda ndi odalirika komanso odalirika, miyezo yokhazikika yokhazikitsidwa yakhazikitsidwa mdziko muno komanso padziko lonse lapansi, yokhudzana ndi katundu, njira zoyesera, ndi mawonekedwe ogwiritsira ntchito.

 

Ku China, mulingo woyambirira wokhazikitsa zosindikizira ndi GB 16776-2005, "Silicone Structural Sealant for Construction." Muyezowu umatchulanso zamagulu, zofunikira zaukadaulo, njira zoyesera, ndi malamulo oyendera a silicone structural sealants, ndipo zimafuna kuti zizindikilo zazikulu monga kulimba kwa chomangira, kusamuka, ndi kukana kukalamba zikwaniritse zofunikira. Mwachitsanzo, muyezo umanena kuti zosindikizira za silikoni ziyenera kukhala zolimba kwa masiku 28 zosachepera 0.6 MPa ndipo ziyenera kuyesedwa kuti zikhale zolimba monga kukalamba ndi kukhudzidwa ndi UV. Kuphatikiza apo, GB/T 14683-2017, "Silicone Building Sealant," imagwiranso ntchito kwa zosindikizira pazogwiritsa ntchito zosamalidwa komanso zimakwaniritsa GB 16776.

Padziko lonse lapansi, ASTM C1184, "Standard Specification for Structural Silicone Sealant," ndi ETAG 002, "Technical Approval Guide for Structural Sealant Assembly Systems," ndi mfundo zodziwika bwino. ASTM C1184 imayika zofunikira mwatsatanetsatane za modulus, elongation, and adhesion of silicone sealants, pamene ETAG 002 imayang'ana kwambiri kuwunika kwachitetezo chonse cha makina ophatikiza makoma, kutsindika kutsimikizira-nthawi yayitali.

Kukhazikitsa mosamalitsa miyezo imeneyi sikungotsimikizira kusasinthika kwa zosindikizira zamapangidwe komanso kumapereka maziko odalirika opangira uinjiniya. M'tsogolomu, ndi kupita patsogolo kwa sayansi yazinthu, miyezo yoyenera ipitilira kukonzedwa kuti ikwaniritse zosowa zamagwiritsidwe ntchito ndi magwiridwe antchito apamwamba komanso zofunikira zachilengedwe.
