연합인증

연합인증 가입 기관의 연구자들은 소속기관의 인증정보(ID와 암호)를 이용해 다른 대학, 연구기관, 서비스 공급자의 다양한 온라인 자원과 연구 데이터를 이용할 수 있습니다.

이는 여행자가 자국에서 발행 받은 여권으로 세계 각국을 자유롭게 여행할 수 있는 것과 같습니다.

연합인증으로 이용이 가능한 서비스는 NTIS, DataON, Edison, Kafe, Webinar 등이 있습니다.

한번의 인증절차만으로 연합인증 가입 서비스에 추가 로그인 없이 이용이 가능합니다.

다만, 연합인증을 위해서는 최초 1회만 인증 절차가 필요합니다. (회원이 아닐 경우 회원 가입이 필요합니다.)

연합인증 절차는 다음과 같습니다.

최초이용시에는
ScienceON에 로그인 → 연합인증 서비스 접속 → 로그인 (본인 확인 또는 회원가입) → 서비스 이용

그 이후에는
ScienceON 로그인 → 연합인증 서비스 접속 → 서비스 이용

연합인증을 활용하시면 KISTI가 제공하는 다양한 서비스를 편리하게 이용하실 수 있습니다.

A dosage size multi-chambered, container having separate sealed compartments is provided and includes constituent materials for forming a wallboard joint compound. The container includes a first compartment containing a first mixture including calcined gypsum, a set preventer and water, and a second compartment sealed from the first compartment with a seal and containing a second mixture including a set initiator and water, wherein upon breaking of the seal, the first and second mixtures are combinable by kneading action to provide a dose of the wallboar...

1. A dosage size multi-chambered container having separate sealed compartments and provided with constituent materials for forming a wallboard joint compound, comprising: a flexible body including a top surface and a bottom surface spaced from said top surface, and a first compartment and a second compartment,said first compartment containing a first mixture including calcined gypsum, a set preventer and water from a single, known water source, wherein said water has known properties to reduce the variation of time of set, said first mixture having a first viscosity, said water not being from a water source at a site where the wallboard joint compound is formed;said second compartment containing a second mixture including a set initiator and said water from the single, known water source, said second mixture having a second viscosity, wherein only one of said first and second mixtures includes a rheology modifier; and said flexible body consisting of:a frangible seal having opposing, internal side surfaces extending between the top surface and the bottom surface of the body, the seal being formed between said first compartment and said second compartment, and configured to break upon application of pressure against one of the side surfaces by a user's hand without rupturing said flexible body, and upon breaking of said seal, said first and second mixtures are readily combined by kneading action to provide a dose of the wallboard joint compound contained in said flexible body that is immediately usable on a surface. 2. The container of claim 1 wherein said first mixture and said second mixture are both liquids. 3. The container of claim 1 further including a pigment in one of said first and second compartments that is indicative of the degree of mixing of said first and second mixtures. 4. The container of claim 3 wherein said pigment is a pH based indicator. 5. The container of claim 3 wherein the pigment is a calcium chelating indicator. 6. The container of claim 1 wherein said seal is breakable and said first and second mixtures are mixable by hand without the use of tools. 7. The container of claim 1 wherein said first mixture includes a latex binder. 8. The container of claim 1 wherein said set initiator is taken from the group consisting of aluminum sulfate, zinc sulfate and iron sulfate. 9. The container of claim 1 further including a third compartment including a second dose of said set initiator and water from said single water source for providing the user with the ability to adjust the rate of setting of the combination of the first and second mixtures. 10. A dosage size multi-chambered container having separate sealed compartments and including constituent materials for forming a wallboard joint compound, comprising: a flexible body consisting of: a top surface and a bottom surface spaced from said top surface;a first compartment containing a first mixture including a calcined gypsum, a set preventer and water from a single, known water source, wherein said water has known properties to reduce the variation in time of set, said first mixture having a first viscosity, said water not being from a water source at a site where the wallboard joint compound is formed; andtwo additional compartments each isolated from said first compartment with frangible seals and each containing an additive for altering the performance of the resulting mixed dose of compound, wherein at least one of said additives includes a set initiator and a thickener and has a second viscosity,each of said frangible seals having opposing, internal side surfaces extending between the top surface to the bottom surface of the body, said frangible seals each being configured to break upon application of pressure against one of the side surfaces of at least one of said seals by a user's hand without rupturing said flexible body, and upon mixing of the first mixture and at least said additive results in a mixture contained within said flexible body that is immediately usable on a surface. 11. A dosage size multi-chambered, flexible container having separate sealed compartments and provided with constituent materials for forming a wallboard joint compound, consisting of: a flexible body including a top surface, a bottom surface spaced from said top surface, and a first compartment and a second compartment,said first compartment containing a first mixture including a slurry of set prevented calcined gypsum, and having a first viscosity; andsaid second compartment sealed from said first compartment with a frangible seal and containing a second mixture including a set initiator, a thickener and water from a single, known water source, wherein said water has known properties to reduce the variation in time of set, and said second mixture having a second viscosity, said water not being from a water source at a site where the wallboard joint compound is formed, said frangible seal having opposing, internal side surfaces extending between the top surface to the bottom surface of the body, and being configured to break upon application of pressure against one of the side surfaces of said seal by a user's hand without rupturing said flexible body, and upon mixing the contents of said first and second compartments, a mixture results that is contained within said flexible body and immediately usable on a surface.
