Zvinhu Zvikuru zveAdhesive Sarudzo

Zvinhu Zvinokosha zveSarudzo Yekunamatira----Technical Principles uye Practical Selection Criteria


Basa rakakosha rezvinonamira ndere kupfekedza nzvimbo dzezvinonamatira uye kuzvibatanidza pamwechete. Paunenge uchigadzira mabhanhire akasungwa, chekutanga chekutanga ndechekusarudza bhandi rakakodzera kubva kumhando dzakasiyana dziripo. Pazasi pane akati wandei akakosha zvinhu zvinopesvedzera sarudzo yekunamatira.

1. I. Bonded Assemblies

Iyo yese yekugadzirisa mafambiro ekugadzira akasungirirwa maassemblies ane madhigirii akasiyana epesvedzero pakusarudza kwekunamira. Pre - bonding processing inogadzira chaiyo yepasi mamiriro pane inonamatira nzvimbo, iyo inotaridza zvakananga iyo yekupedzisira bonding kuita. Kana mamiriro akadaro epamusoro asingagoni kuchinjwa, chisungo chinopindirana nepamusoro chiripo chinofanira kusarudzwa. Post - bonding machining maitiro eiyo yakapedzwa yakasungwa chikamu inodawo kuverengerwa panguva yekunamira kusarudzwa. Kana gungano rakasungirirwa rinoshanda sechikwata chimwe chete kuti chibatanidzwe nezvimwe zvikamu, maitiro ekubata edhesi yakasarudzwa inofanira kuenderana nekugadzirwa kwemaitiro emamwe maitiro ekushanda. Mukuwedzera, chimiro chemuviri chekunamatira (mvura, paste, firimu kana yakasimba) ichafananidza nzira dzekugadzira dzinoshandiswa pamusangano wakasungwa.

1. II. Properties of Adherend Materials

Izvo zvepanyama uye zvemakemikari zvinhu zveadherend zvinhu, pamwe chete nezvinodiwa pamusoro pekugadzirisa chiyero chisati chabatanidzwa, chinoumba chimwe chinhu chakakosha pakusarudza kwekunamatira.Chinangwa chekusarudza panguva ino ndechekuwedzera simba rekubatanidza kumativi ose ekubatanidza, kuitira kuti chibatanidza chinokundikana kuwirirana panguva yekuedzwa pane kutambura kukanganisa kwepakati pakati pekunamatira uye kunamatira. Nenzira iyi chete iyo simba guru rekunamatira rinogona kuzadzikiswa zvizere.

1. III. Kusimba Kwekunamatira Zvishandiso

Low-simba substrates inogona kunge isina kusimba pane inonamira pachayo, zvichikonzera kukanganisa kwakabatana kunoitika mukati meiyo adherend pachinzvimbo chekunamatira layer.

Nokuda kwezvikumbiro zvakadaro, iyo yakanamatira yakasarudzwa ichabvumira gungano rakasungirirwa kuti rimirire mamiriro ose ebasa remuviri izvo nheyo yezvinhu inogona kutsungirira, pasina njodzi yekukundikana kwekubatana. Muchiitiko ichi, kutora yakakwirira-kunamira kwesimba kwaizotungamira kune pamusoro-kutsanangurwa kwezvinhu zvinonamatira uye zvisingakoshi zvekuwedzera mari.

1. IV. Hukobvu hweAdherend Materials

Chimwe chinhu chisingagoni kuregererwa chimiro chemuviri chekunamatira. Solvent-based adhesives inowanzokonzera kuunyana pamicheto yemajoini kana ichibatanidza mafirimu ethermoplastic kana malaminates awo akaumbwa; zvisinei, kana ikaiswa kune yakaoma thermoplastics, inowanzo dzikisa zvinodiwa zve substrate surface pretreatment. Iyo yakakosha geometry yeadherends inowanzo fambisa kushandiswa kwemhando dzakanamira dzeanonamatira. Kune kumucheto chisungo pakati pealuminium huchi zvimiro uye flat simbi mashiti, yemvura primer yakabatanidzwa ne thermosetting adhesive mafirimu akasimbiswa nefiberglass jira rinounza kwakaringana bonding kuita. Namatidza zvinonamira zviri nyore kugadzira zvinopisa zvinopisa nekujoinha zvimbi zvemhangura nemachubhu ealuminium. Kune porous substrates, yakakwirira-viscosity kana paste-mhando yekunamira ndiyo inonyanya kukodzera

1. V. Kugarisana Pakati Pemadherends uye Adhesives

Kusapindirana pakati peadherend uye kunamatira kuchaita kuti kukanganiswa kwekubatanidza kwegungano rakasungwa. Izvi zvine chokwadi kunyangwe chikamu chimwe chete chekunamatira chisingaenderane neanonamatira. Mienzaniso yakaita seiyi: masimbi ari kuita ngura nemanamira ane acidic kana alkaline; mapurasitiki ari kutama kubva mumapurasitiki anochinjika kupinda mune inonamira uye zvichikonzera kukanganisa kwekubatana kwemukati; zvinonyungudutsa kana zvinhu zvinoputika zviri muinamira zvinorwisa mafirimu epurasitiki. Naizvozvo, pese pazvinogoneka, zvakatsanangurwa zvezvivakwa zvinopihwa pamwe chete nemasampuli anonamira. Izvi pasina mubvunzo zvichabatsira vese vanonamatira vanogadzira uye matekinoroji anoita bonding maitiro.

1. VI. Zvinodiwa Pakuchengeta Magungano Akasungirirwa

Nepo mamiriro ebasa emagungano akasungwa kazhinji anokwevera tarisiro yakakwana, mamiriro avo ekuchengetedza anowanzo furatirwa. Chiitiko chakakodzera ndechekufunga nezve tembiricha yakanyanyisa uye inokanganisa mitoro iyo yakasungwa magungano inogona kusangana panguva yekufambisa uye kuchengetedza padanho rekunamatira.

1. VII. Mutengo

Paunenge uchiongorora iyo yese yekubatanidza maitiro seyese, kukodzera kwenzvimbo yekunamatira inotakura huremu hukuru kupfuura mutengo wayo. Kupfuura mutengo weyuniti yekunamatira pachezvayo, kugona kwekugadzira uye zvimwe zvinosanganisirwa zvinhu zvinofanirwa kuverengerwa mukuita sarudzo. Kungosarudza yakachipa inonamira pasina kutarisisa maitiro akakodzera akanyorwa pazasi hazvizoiti kuunza mabhenefiti akanaka ehupfumi:

Pakazara bonding kunyatsoshanda

Kureruka kwekutora michina inodiwa pakunyorera uye kugadzirisa

Nguva yekutenderera inopedzwa nemaitiro ekubatanidza

Mari yevashandi yekunamatira kuungana uye kuongorora

Waste generation volume ichienzaniswa nemamwe majoining tekinoroji

Kazhinji, kukurumidza - matinji anonamira anogonesa kurerutswa bonding workflows anodhura
